## Description: Apache HBase is an open-source, distributed, versioned, non-relational database. Apache HBase gives you low latency random access to billions of rows with millions of columns atop non-specialized hardware. hbase-thirdparty is a set of internal artifacts used by the project to mitigate the impact of our dependency choices on the wider ecosystem. hbase-connectors is a collection of integration points with other projects. The initial release includes artifacts for use with Apache Kafka and Apache Spark. hbase-filesystem contains HBase project-specific implementations of the Apache Hadoop FileSystem API. It is currently experimental and internal to the project. hbase-operator-tools is a collection of tools for HBase operators. Now it is mainly for hosting HBCK2. hbase-native-client is a client library in C/C++, in its early days. hbase-kustomize is for deploying HBase on kubernetes, still under development. ## Project Status: Current project status: Ongoing Issues for the board: There is a request from the trademarks team about missing the 'TM' superscript for some web pages on hbase.a.o. https://lists.apache.org/thread/ncp2kv5shjnkm3zq20v5ft94fnwr8fv4 The issue has already been resolved. ## Membership Data: Apache HBase was founded 2010-04-21 (14 years ago) There are currently 104 committers and 59 PMC members in this project. The Committer-to-PMC ratio is roughly 7:4. Community changes, past quarter: - Bryan Beaudreault was added to the PMC on 2023-10-17 - No new committers. Last addition was Hui Ruan on 2023-09-15. ## Project Activity: 2.5.7 was released on 2023-12-24. hbase-connectors-1.0.1 was released on 2023-10-27. 2.5.6 was released on 2023-10-20. We have cut branch-2.6 and started to prepare the 2.6.0 release. There were some discussions around the hadoop versions we want to support https://lists.apache.org/thread/rt2ht8xmmr9vp77trsbs1db6f90pbpm8 We decided to follow the hadoop community, move the minimum hadoop 3 support to 3.3.x, but for hbase-2.x, we still have support for 2.10.2, though there are some CVEs. We upgraded zookeeper dependencies to 3.8.x in a patch release due to some CVEs, and it should be much less hurt than upgrading Hadoop. https://lists.apache.org/thread/pbjfs75kpkd3y9dcydhmr2lotnv72s8w There will be a HBase meetup in India. https://lists.apache.org/thread/n8bb8tzghcxgg7w8fd80542fo9x6mmr9 ## Community Health: dev@hbase.apache.org: 960 subscribers(958 in the previous quarter) 420 emails sent to list(360 in the previous quarter) user@hbase.apache.org: 1986 subscribers(1988 in the previous quarter) 31 emails sent to list(39 in the previous quarter) user-zh@hbase.apache.org 77 subscribers(78 in the previous quarter) 17 emails sent to list(19 in the previous quarter) - JIRA activity: 108 issues opened in JIRA, past quarter (-36% change) 75 issues closed in JIRA, past quarter (-32% change) - Commit activity: 464 commits in the past quarter (20% increase) 40 code contributors in the past quarter (-4% change) - GitHub PR activity: 160 PRs opened on GitHub, past quarter (4% increase) 145 PRs closed on GitHub, past quarter (no change) The community is overall healthy. It is Christmas so recently the numbers decreased a lot. We have cut branch-2.6 and planned to put up 2.6.0 release candidate soon. And the vote for 3.0.0-beta-1 is ongoing.

We have finished the presentation 'What's new in the recent and upcoming HBase releases' on CoC Asia 2023. https://issues.apache.org/jira/browse/HBASE-27910 https://www.bilibili.com/video/BV1CN411H7Af There are no new HBase releases this quartar. There are several regressions which stops the new releases. We are busy working on fixing them. The plan is to make the 2.5.6 release first, then cut branch-2.6 and release 2.6.0, and then release 2.4.17 and mark branch-2.4 as EOL. https://lists.apache.org/thread/bpnjwh8rjckwcn1dw3245r7ngcw49rj3 https://lists.apache.org/thread/ks0hdrpqhjkccb7ybt2x319onwcvzd4m https://lists.apache.org/thread/6y6v746533j854q19bstvj24s7y74k5n https://lists.apache.org/thread/tsszxm7gq04o3kvmk3s4kfxnddp3hhn1 https://lists.apache.org/thread/k77yr3r4fwkrrt5jb187oswz2qgcfj63 ## Community Health: - Mailing list activity: dev@hbase.apache.org: 958 subscribers(958 in the previous quarter) 360 emails sent to list(490 in the previous quarter) user@hbase.apache.org: 1988 subscribers(1990 in the previous quarter) 39 emails sent to list(42 in the previous quarter) user-zh@hbase.apache.org 78 subscribers(78 in the previous quarter) 19 emails sent to list(50 in the previous quarter) - JIRA activity: 166 issues opened in JIRA, past quarter (-10% change) 113 issues closed in JIRA, past quarter (-18% change) - Commit activity: 386 commits in the past quarter (-33% decrease) 42 code contributors in the past quarter (5% increase) - GitHub PR activity: 149 PRs opened on GitHub, past quarter (-16% change) 146 PRs closed on GitHub, past quarter (-3% change) The community is overall healthy. The numbers are decreased since many community members were on vacation during August and September. We are approaching the final stages of preparing to cut branch-2.6 and create the first beta release for the 3.0.0 release line. I am hopeful that we can accomplish these milestones during the last quarter of 2023.

In the recent board report feedback, a board member suggested that we'd better filter out the jira notification email from the dev list, otherwise it is really hard to find out useful information. So we started a discussion thread in the dev list about this, and the community members prefered to keep it as is. We only send open/close notifications to the dev list and it is useful to keep informed about what's happening. https://lists.apache.org/thread/0wo98q9j93mkvn61wcwppwhkgfjm7mdn We successfully held an online meet up on 04/19/2023, and discussed many interesting topics. https://lists.apache.org/thread/ostq5zqx96s7c2g3mdflvtzj6781orsh We moved the stable pointer to 2.5.x. https://lists.apache.org/thread/5crkzzxcnb471w4p0wqhppmjmln66pkd We finally resolved all pending big features for 3.x and cut branch-3. https://lists.apache.org/thread/np9bkln30zqm50k332h8bsjrtgzr9691 For better support for deploying HBase on top of kubernetes, we decided to introduce a new repository for the kustomize files. https://lists.apache.org/thread/wc0hs5pmhrcczox4ddl0942pd59sho6x We submitted a presentation 'What's new in the recent and upcoming HBase releases' to Community Over Code Asia 2023. https://lists.apache.org/thread/fk1tr0sfk3zwbxxqcol3sbqz81mfdmrx https://issues.apache.org/jira/browse/HBASE-27910 ## Community Health: - Mailing list activity: dev@hbase.apache.org: 958 subscribers(959 in the previous quarter) 490 emails sent to list(595 in the previous quarter) user@hbase.apache.org: 1990 subscribers(1987 in the previous quarter) 42 emails sent to list(43 in the previous quarter) user-zh@hbase.apache.org 78 subscribers(78 in the previous quarter) 50 emails sent to list(43 in the previous quarter) - JIRA activity: 183 issues opened in JIRA, past quarter (-17% change) 138 issues closed in JIRA, past quarter (-14% change) - Commit activity: 579 commits in the past quarter (-1% decrease) 40 code contributors in the past quarter (-23% change) - GitHub PR activity: 179 PRs opened on GitHub, past quarter (-21% change) 149 PRs closed on GitHub, past quarter (-36% change) We are pleased to announce the long-awaited release of 3.0.0-alpha-4 and the completion of branch-3. This represents a significant milestone in the progress towards the final release of 3.0.0. In the 2.6.0 release, we have successfully addressed multiple issues; however, there is still one critical problem remaining. Under high load conditions, the server may encounter out-of-memory errors if TLS is enabled. Fortunately, we have already identified potential solutions, and we are optimistic that we will be able to release 2.6.0 in the coming months.

The Ozone community started to work on support writing HBase WAL to Ozone. So in the future we can run HBase fully on Ozone, without deploying a small HDFS cluster for writing WAL. https://lists.apache.org/thread/tcrp8vxxs3z12y36mpzx35txhpp7tvxv The infra team delivered a self serving page for requesting jira account, so we changed our README.md again. https://lists.apache.org/thread/cvt50odv820j67167os3ckb9j6nftgms https://issues.apache.org/jira/browse/HBASE-27689 We planned to hold a hybrid (physical and virtual) meetup in April, to discuss several technical topics, and also what are we going to do in ApacheCon/Community Over Code in October. https://lists.apache.org/thread/xolczzstp4pzplrtfjkssk69jgs5wxj3 ## Community Health: - Mailing list activity: dev@hbase.apache.org: 959 subscribers(956 in the previous quarter) 599 emails sent to list(434 in the previous quarter) user@hbase.apache.org: 1987 subscribers(1987 in the previous quarter) 43 emails sent to list(59 in the previous quarter) user-zh@hbase.apache.org 78 subscribers(78 in the previous quarter) 43 emails sent to list(18 in the previous quarter) - JIRA activity: 224 issues opened in JIRA, past quarter (62% increase) 160 issues closed in JIRA, past quarter (26% increase) - Commit activity: 588 commits in the past quarter (40% increase) 51 code contributors in the past quarter (24% increase) - GitHub PR activity: 227 PRs opened on GitHub, past quarter (66% increase) 230 PRs closed on GitHub, past quarter (75% increase) While the numbers showed improvement compared to the previous quarter, we are still working on releasing versions 2.6.0 and 3.0.0-alpha-4. Despite this, we have made progress towards these two releases this quarter. Various groups of contributors in the community have begun deploying and testing HBase with mTLS support, a key feature in. Additionally, we successfully completed the most challenging sub-task for HBASE-27109, which is part of 3.0.0-alpha-4. This progress makes us optimistic that we will soon be able to release both versions.

We finally find a way to publish binaries and artifacts compiled with hadoop3. The guys from the Phoenix community confirmed that the solution worked perfectly. And the Hudi project could also be benefited. https://lists.apache.org/thread/y05gspk4mnxsz6nk7hc5ots8wt50366b https://issues.apache.org/jira/browse/HBASE-27434 https://issues.apache.org/jira/browse/HBASE-27442 https://github.com/apache/hbase/pull/4917 The self registration of jira.a.o had been closed by infra team due to spam, unfortunately HBase uses jira for issuing track. After discussion, we decided to let users send a request email to private@hbase and let PMC members to request a jira account for the contributor. We also changed our readme page to mention this change. https://lists.apache.org/thread/vgy1n8brdoxqg9qs7752hg8otjcnhyoz https://issues.apache.org/jira/browse/HBASE-27513 ## Community Health: - Mailing list activity: dev@hbase.apache.org: 956 subscribers(952 in the previous quarter) user@hbase.apache.org: 1987 subscribers(1994 in the previous quarter) user-zh@hbase.apache.org 78 subscribers(77 in the previous quarter) - JIRA activity: 128 issues opened in JIRA, past quarter (-46% change) 120 issues closed in JIRA, past quarter (-42% change) - Commit activity: 413 commits in the past quarter (-28% change) 42 code contributors in the past quarter (-14% change) - GitHub PR activity: 132 PRs opened on GitHub, past quarter (-42% change) 126 PRs closed on GitHub, past quarter (-48% change) We now have more than 400 invididual contributors(401 till now) on the github statistic page! The development activity was still decreased. This is partly because we are still waiting for the final features to be landed on master and branch-2, i.e, the replication improvements and backup support, so we can cut branch-3 and branch-2.6 and start to making 3.0.0 and 2.6.0 release. Hope we can cut these two branches in the next quarter and make more releases.

We released 2.5.0, which is the first release of the 2.5.x release line. We released 1.7.2 and finally EOLed all the 1.x release lines. We are currently preparing the 2.6.0 release which contains TLS support, hope we could release 2.6.0 in the next few months. 3.0.0-alpha-4 is still waiting some features to be landed, hope we could release it by the end of year.

We met some difficulty when releasing 2.5.0, it is about memory leak. We reported the issue to netty and the netty community also helped. https://issues.apache.org/jira/browse/HBASE-26708 https://github.com/netty/netty/issues/12549 https://github.com/apache/hbase/pull/4597 We landed the spotless changes, it reduced the checkstyle errors a lot, but developers in the community still need to get used to this new tool. https://issues.apache.org/jira/browse/HBASE-26617 https://issues.apache.org/jira/browse/HBASE-26899 https://issues.apache.org/jira/browse/HBASE-27023 https://lists.apache.org/thread/700n1wv877q5l35rbqmtl8qf2w0kjxqz We made 3.0.0-alpha-3 release and also discussed the plan for the last alpha release of 3.0.0. https://lists.apache.org/thread/2tkvv1pz94wyx5kq4h1vmjj0c267zvjl ## Community Health: - Mailing list activity: dev@hbase.apache.org: 948 subscribers(953 in the previous quarter) user@hbase.apache.org: 2000 subscribers(2001 in the previous quarter) user-zh@hbase.apache.org 75 subscribers(74 in the previous quarter) - JIRA activity: 236 issues opened in JIRA, past quarter (-20% change) 1675 issues closed in JIRA, past quarter (536% increase) - Commit activity: 615 commits in the past quarter (-22% decrease) 47 code contributors in the past quarter (-4% change) - GitHub PR activity: 278 PRs opened on GitHub, past quarter (-20% change) 264 PRs closed on GitHub, past quarter (-21% change) The number of the mailing list trends seems incorrect, the graph shows there is a significant increase of the dev@hbase but the number is still 897, where the board reports of Jan and Apr also had a number of 897, so I do not post them above. We closed a bunch of issues which have been included in old releases and resolved for a long time, this is the reason why the traffic in dev list has increased a lot. As said above, the 2.5.0 release was blocked by a critial memory leak problem for quite a well. We released 3.0.0-alpha-3 and plan to release 3.0.0-alpha-4 in the coming quartar. Hope in the next few month we could release 2.5.0, EOL 1.x, and cut branch-3 for releasing beta releases of 3.x.

But looking at the status.apache.org page, there is no record about this outage. So we wonder whether the current availabilty metrics is enough to reflect the real 'availability' of our system. ## Membership Data: Apache HBase was founded 2010-04-21 (12 years ago) There are currently 98 committers and 56 PMC members in this project.

We decided to use spotless to auto format our code to make our contributor easier to fix the checkstyle issues when submitting PR. https://lists.apache.org/thread/5r1kgmqkkgch8zx6wmhjvlv1kjdy9h59 We talked about whether to EOM branch-1, no final decision has been made but we agreed to make a 1.7.2 release and checked again on 2022.7.21. https://lists.apache.org/thread/8qy2lqtdwzc10tqnfdhrqvo35z6vkrvk We talked about removing JDK8 support on master branch and finally we found a way to compile with JDK11 but still maintain compatilibity with JDK8 https://lists.apache.org/thread/w5lrxkhswlonj09xf9hcwgvck3nsjdfx https://issues.apache.org/jira/browse/HBASE-25465 We talked about which logging framework to use. The candidates were reload4j, logback and log4j2. After some important improvements in log4j2, finally we migrated all the new release lines to use log4j2. We still need to test the log4j1 compability in the future. https://lists.apache.org/thread/kfmjg6zmvdjqcwolj0oh634nzv42y806 https://lists.apache.org/thread/gvfb3jkg6t11cyds4jmpo7lrswmx28w3 https://issues.apache.org/jira/browse/HBASE-26802 https://issues.apache.org/jira/browse/LOG4J2-3341 https://issues.apache.org/jira/browse/LOG4J2-3394 We talked about how to better maintain our ref guide as we kept removing the information for EOM release lines from the ref guide but the per release line ref guide is not well maintained. The final decision is to only maintain the ref guide on master branch and include all the information in it, include the EOM release lines. https://lists.apache.org/thread/bd6x1gnpgh0p3n4c2bnr1m4qpp7xxclc https://issues.apache.org/jira/browse/HBASE-26930 ## Community Health: - Mailing list activity: dev@hbase.apache.org: 953 subscribers(955 in the previous quarter) 897 emails sent to list(897 in the previous quarter) user@hbase.apache.org: 2001 subscribers(2010 in the previous quarter) 88 emails sent to list(88 in the previous quarter) user-zh@hbase.apache.org 74 subscribers(72 in the previous quarter) 10 emails sent to list(10 in the previous quarter) - JIRA activity: 278 issues opened in JIRA, past quarter (-11% decrease) 247 issues closed in JIRA, past quarter (-10% decrease) - Commit activity: 738 commits in the past quarter (-21% increase) 49 code contributors in the past quarter (-23% increase) - GitHub PR activity: 325 PRs opened on GitHub, past quarter (2% increase) 313 PRs closed on GitHub, past quarter (no change) The community is overall health. The 2.5.0 release is delayed because we want to put more features to it, like better cloud object storage support, and also because we spent sometime to decide which logging framework to use, reload4j, logback or log4j2.And all these problems have been solved so we can expect the 2.5.0 release to come out soon.
## Description: Apache HBase is an open-source, distributed, versioned, non-relational database. Apache HBase gives you low latency random access to billions of rows with millions of columns atop non-specialized hardware. hbase-thirdparty is a set of internal artifacts used by the project to mitigate the impact of our dependency choices on the wider ecosystem. hbase-connectors is a collection of integration points with other projects. The initial release includes artifacts for use with Apache Kafka and Apache Spark. hbase-filesystem contains HBase project-specific implementations of the Apache Hadoop FileSystem API. It is currently experimental and internal to the project. hbase-operator-tools is a collection of tools for HBase operators. Now it is mainly for hosting HBCK2. hbase-native-client is a client library in C/C++, in its early days. ## Issues: There are no issues requiring board attention. ## Membership Data: Apache HBase was founded 2010-04-21 (12 years ago) There are currently 96 committers and 56 PMC members in this project. The Committer-to-PMC ratio is roughly 3:2. Community changes, past quarter: - No new PMC members. Last addition was Bharath Vissapragada on 2021-07-30. - Huang Zhuoyue was added as committer on 2021-10-14 ## Project Activity: Recent releases: hbase-thirdparty-4.0.1 was released on 2021-12-28. 2.4.9 was released on 2021-12-24. hbase-operator-tools-1.2.0 was released on 2021-12-24. 3.0.0-alpha-2 was released on 2021-12-23. hbase-thirdparty-4.0.0 was released on 2021-12-10. 2.4.8 was released on 2021-11-03. 1.4.14 was released on 2021-10-25. 2.3.7 was released on 2021-10-19. 2.4.7 was released on 2021-10-18. We have received a new donation and infra is currently setting up a new dedicated jenkins controller for us. https://s.apache.org/i1rox The HBASE-26067 feature branch has been merged back to master and branch-2. It makes HBase work better with cloud object stores which is very useful for the cloud users and is a big step on making HBase cloud native. https://issues.apache.org/jira/browse/HBASE-26067 https://issues.apache.org/jira/browse/HBASE-26584 https://s.apache.org/2slqr https://s.apache.org/nk6vr The HBASE-26233 feature branch has been merged back to master. It greatly reduces the latency of our region replication feature, and is also the first step of decoupling the WAL system and replication framework, which is very important for making HBase fully cloud native. https://issues.apache.org/jira/browse/HBASE-26233 https://s.apache.org/8q7h1 https://s.apache.org/die6s We were also affected by the log4j2 vulnerabilities. Luckily our stable release lines are still on log4j1. We released 3.0.0-alpha-2 and hbase-operator-tools-1.2.0 for addressing the vulnerabilities. In one of the release vote thread, the community members discussed whether we'd better switch to logback instead of log4j2, or make HBase 'logging framework free'. No decisions have been made so far. https://s.apache.org/r1lbk https://s.apache.org/53800 We have marked 2.3.x EOL and moved the stable pointer to 2.4.x. https://s.apache.org/gbm4b https://s.apache.org/5r5wq We have made the final 1.4.14 release for 1.4.x release line and marked 1.4.x EOL. https://s.apache.org/znnxw ## Community Health: - Mailing list activity: dev@hbase.apache.org: 955 subscribers(957 in the previous quarter) 897 emails sent to list(747 in the previous quarter) user@hbase.apache.org: 2010 subscribers(2017 in the previous quarter) 88 emails sent to list(95 in the previous quarter) user-zh@hbase.apache.org 72 subscribers(72 in the previous quarter) 10 emails sent to list(11 in the previous quarter) - JIRA activity: 308 issues opened in JIRA, past quarter (17% increase) 263 issues closed in JIRA, past quarter (19% increase) - Commit activity: 914 commits in the past quarter (39% increase) 61 code contributors in the past quarter (19% increase) - GitHub PR activity: 304 PRs opened on GitHub, past quarter (7% increase) 294 PRs closed on GitHub, past quarter (3% increase) The increase of the numbers is partly because we merged two feature branches back. And the log4j2 vulnerabilities also contribute extra traffic on our dev mailing list as we have to keep publishing new RCs when there are new log4j2 releases out. Currently we are looking forward on the first 2.5.x release and the first beta release for 3.0.0.

We are actively considering EOL for the 2.3.x release line. https://s.apache.org/i56se The work for better support object store had a good progress, we decided to implement a general framework which could support different implementations. https://issues.apache.org/jira/browse/HBASE-26067 https://s.apache.org/zh8ei https://s.apache.org/7hssk https://s.apache.org/7thaz We finally made our first alpha release for the 3.x release line. https://s.apache.org/74sc5 We got trouble in our jenkins jobs as they would report an unstable result when everything is fine, finally we found that it was a bug in the surefire plugin, but so far there is no progress on fixing. https://s.apache.org/mmsmo https://issues.apache.org/jira/browse/SUREFIRE-1821 We had some discussions on the InterfaceStability and InterfaceAudience annotations and related modules, and the Yetus community planned to remove these annotations because they want to drop the support for JDK8. We are not yet sure as a community what approach we'll take. https://s.apache.org/bi8qv https://s.apache.org/nhvni https://s.apache.org/uqae1 We backported the open telemetry support to branch-2, and it will be a key feature for our 2.5 release line. https://s.apache.org/9hd86 There was a big improvement on compression support in HBase. We introduced several new modules to better support different compression codecs. https://issues.apache.org/jira/browse/HBASE-26259 We had been pinged by the infra again about eating all the spaces on jenkins nodes, and this time we made some good progress on uploading the big files to nightlies.apache.org. https://issues.apache.org/jira/browse/HBASE-24936 The members in the community had posted several blogs about different modules in HBase. https://s.apache.org/b18si https://s.apache.org/45ymf ## Community Health: - Mailing list activity: dev@hbase.apache.org: 957 subscribers(955 in the previous quarter) 747 emails sent to list(769 in the previous quarter) user@hbase.apache.org: 2017 subscribers(2021 in the previous quarter) 95 emails sent to list(100 in the previous quarter) user-zh@hbase.apache.org 72 subscribers(73 in the previous quarter) 11 emails sent to list(9 in the previous quarter) - JIRA activity: 248 issues opened in JIRA, past quarter (-24% change) 203 issues closed in JIRA, past quarter (-21% change - Commit activity: 605 commits in the past quarter (-17% decrease) 52 code contributors in the past quarter (-16% change) - GitHub PR activity: 263 PRs opened on GitHub, past quarter (-24% change) 261 PRs closed on GitHub, past quarter (-16% change) The community is overall healthy, we should try to cut branch-2.5 and make the next alpha release for 3.0.0 soon.

We discussed again on whether to EOL all 1.x, as There doesn't seem to be much developer interest in branch-1 beyond occasional maintenance. Reid Chan offered to complete the 1.7.0 release. https://s.apache.org/u3q4t We restarted the splittable meta design, and held an online meeting again to discuss. https://s.apache.org/i5mwy We discussed whether to move the stable pointer to 2.4.x. This is a good sign that the 2.x releases are more and more stable. https://s.apache.org/z1iaq The volunteer on maintaining hbase-backup had shown up and put up a design discussion about the feature. https://s.apache.org/ora3e We found that it is a bit pain for keeping JIRA issue and git commit in sync and what's more, we include CHANGES and RELEASENOTES directly in a release so it will be easy to sink an RC if we found something wrong in these two files, not the actual code. We discussed how to make RMs live better in the future. https://s.apache.org/2nxzw The first phase of moving our tracing system from HTrace to OpenTelemetry has been done. We will start a vote soon to merge the feature branch back. https://s.apache.org/9eekz We finally migrated the legacy log4j1 logging system to log4j2.

A new minor release line 2.4.x has been established, which is the fifth minor release line for 2.x. We discussed whether to purge the hbase-backup module because it has not been included in any releases and now lack maintenance and there was a user in the community who wanted to maintain it. https://s.apache.org/k5b9i We discussed how to better make use of 'Signed-off-by' in the commit message. There is no consensus so far, mainly because whether to use 'Reviewed-by' instead of 'Signed-off-by' for non committer reviewers. https://s.apache.org/tgjup We decided to move the stable pointer to 2.3.x and EOL the 2.2.x release line.

This means 2.x is getting more and more stable and no big new features for 2.x. This is a sign that we may need to kick the 3.0.0 release. A good news is that the number of contributors remained at the same level.

They are under the 'hbase' label of ci-hadoop.a.o. We migrated several jenkins jobs to the new build machines so we will not eat too many resources of the shared H nodes which are used by all Hadoop related projects. Thanks to the infra team, especially Gavin McDonald for setting up the nodes and helping fixing problems. https://ci-hadoop.apache.org/label/hbase/ https://issues.apache.org/jira/browse/HBASE-25106 We had a tough collaboration problem across developers who had different opinions about how to implement a new feature. There are basically two ways to solve the problem and we could not reach an agreement on which way to go.

We got some new commits for cleaning up the build system and testing. 2020-4-21 is our 10th anniversary, the foundation posted a blog about it https://s.apache.org/m2pxf Josh Elser has done a feathercast to talk about the history and the current state of HBase. https://s.apache.org/1m3gw We discussed about 'Removing problematic terms from our project' https://s.apache.org/cpk1y Of the four individual proposals articulated in this discussion, there is consensus on three, and differing opinions on the fourth, but sufficient numbers of PMC have been supportive to sustain a release vote, unless the vote becomes controversial, which we can deal with at the time. There is sufficient support to move forward with contributions on the JIRAs highlighted in the discussion. ## Community Health: - Mailing list activity: dev@hbase.apache.org: 983 subscribers(986 in the previous quarter) 1599 emails sent to list(1262 in the previous quarter) user@hbase.apache.org: 2080 subscribers(2100 in the previous quarter) 173 emails sent to list(174 in the previous quarter) user-zh@hbase.apache.org 63 subscribers(49 in the previous quarter) 19 emails sent to list(21 in the previous quarter) - JIRA activity: 550 issues opened in JIRA, past quarter (16% increase) 406 issues closed in JIRA, past quarter (36% increase) - Commit activity: 1318 commits in the past quarter (-9% decrease) 85 code contributors in the past quarter (26% increase) - GitHub PR activity: 608 PRs opened on GitHub, past quarter (30% increase) 584 PRs closed on GitHub, past quarter (36% increase) The development is still very active, and a good sign is that we have more contributors this quarter.

Last addition was Guangxu Cheng on 2019-12-09. - Bharath Vissapragada was added as committer on 2020-02-06 ## Project Activity: Apache HBase was founded at 2010-4-21, so 2020-4-21 is our 10th anniversary! Recent releases: 2.2.4 was released on 2020-03-11. 1.6.0 was released on 2020-03-06. 1.4.13 was released on 2020-02-29. 2.1.9 was released on 2020-02-17. 2.2.3 was released on 2020-01-10. We finally cut branch-2.3 and will mark branch-2.1 as EOL after the final 2.1.10 release. https://s.apache.org/2630z https://s.apache.org/dyojo https://s.apache.org/l8v2v https://s.apache.org/d4w2f We moved stable pointer to 2.2.x, and created a stable-1 pointer to 1.4.x. https://s.apache.org/geeg3 And after reconsideration, we decided to remove the stable-1 pointer. https://s.apache.org/ync5i There was a discussion about the release plan of 3.0.0 https://s.apache.org/2vs5g We created a user-zh mailing list for users to communicate with Chinese. https://s.apache.org/jnjl8 ## Community Health: - Mailing list activity: dev@hbase.apache.org: 986 subscribers(990 in the previous quarter) 1262 emails sent to list(1157 in the previous quarter) user@hbase.apache.org: 2100 subscribers(2121 in the previous quarter) 174 emails sent to list(144 in the previous quarter) user-zh@hbase.apache.org 49 subscribers 21 emails sent to list - JIRA activity: 455 issues opened in JIRA, past quarter (26% increase) 280 issues closed in JIRA, past quarter (8% increase) - Commit activity: 1400 commits in the past quarter (45% increase) 68 code contributors in the past quarter (-6% decrease) - GitHub PR activity: 437 PRs opened on GitHub, past quarter (32% increase) 407 PRs closed on GitHub, past quarter (32% increase) The mailing list activity remained, it is a good news that we did not suffer too much from the COVID-19. The development activity had a significant increasing. This is because we were preparing the 2.3.0 release, and the stabilizing work introduced a lot of commits.

There are lots of users still on branch-1.x, there were some discussions about the release plan for branch-1.x. About the versioning and 1.5.1 release https://s.apache.org/krmcu About the EOL of branch-1.3 https://s.apache.org/b2jac We decided to use GitHub PR instead of Review Board officially, since Review Board is only available to committers now. https://s.apache.org/mkkld We decided to cut branch-2.3 soon and EOL branch-2.1, Nick Dimiduk volunteered to be the release manager of branch-2.3. https://s.apache.org/bwr9g We discussed the hadoop versions and release plan for 3.0.0, Sean Busbey volunteered to be the release manager of 3.0.0 and start to make alpha releases for 3.0.0. https://s.apache.org/gih8e https://s.apache.org/u4lfo ## Community Health: - Mailing list activity: dev@hbase.apache.org: 990 subscribers(1015 in the previous quarter) 1157 emails sent to list(1297 in the previous quarter) user@hbase.apache.org: 2121 subscribers(2150 in the previous quarter) 144 emails sent to list(268 in the previous quarter) - JIRA activity: 312 issues opened in JIRA, past quarter (-37% decrease) 211 issues closed in JIRA, past quarter (-46% decrease) - Commit activity: 834 commits in the past quarter (-53% decrease) 73 code contributors in the past quarter (-22% decrease) - GitHub PR activity: 297 PRs opened on GitHub, past quarter (-27% decrease) 267 PRs closed on GitHub, past quarter (-36% decrease) I think the number decreasing is partly because the long holiday in China in October, and also the Chrismas holiday in some western countries in December. And also, since branch-2 gets more and more stable, the number of bug fixes will also be decreased day by day. We have already started to make the 3.0.0 release and bring more new features to the community.

Community changes, past quarter: - Zheng Hu(openinx) was added to the PMC on 2019-08-05 - Reid Chan(reidchan) was added to the PMC on 2019-08-12 - Pankaj Kumar(pankajkumar) was added as committer on 2019-09-13 - Sakthi(sakthi) was added as committer on 2019-08-01 - Tak-Lon (Stephen) Wu(taklwu) was added as committer on 2019-08-06 The PMC Chair was changed on 2019-07. Misty Linville stepped back and Duo Zhang was appointed as the new Chair. Thanks Misty for serving us as Chair in the last two years. ## Project Activity: Recent releases: hbase-thirdparty-3.0.0 was released on 2019-09-25. hbase-operator-tools-1.0.0 was released on 2019-09-24. 2.2.1 was released on 2019-09-04. 2.1.6 was released on 2019-08-30. 2.0.6 was released on 2019-08-19. HBase 2.0.x is at the end of maintenance (EOM). 2.0.x users are encouraged to upgrade to the the newest 2.1.x and 2.2.x releases. HBaseConAsia 2019 was held on 2019-07-20 in Beijing, China. There are roughly 500+ attendees and more than 20 presentations. A simple report: https://lists.apache.org/thread.html/fe68ed3a1c4e54821d48e77a8e69885d1709a82c00ae7b493910fa4e@%3Cdev.hbase.apache.org%3E We also had a round table meeting on the day after the conference, this is the meeting note: https://lists.apache.org/thread.html/3d5fe9a80fa4876688d4dba96dff63de95cad8c2442873aed38f96ca@%3Cdev.hbase.apache.org%3E There were some discussions about the relationship between HBase and Phoenix. We revived the discussion about moving the stable pointer to 2.x https://lists.apache.org/thread.html/81b2917eba3fce2872b96526635a5ba11535c73641cb3d38271ee353@%3Cdev.hbase.apache.org%3E https://lists.apache.org/thread.html/f9ae2bf212d4d1c48eecf3d1d26edb0dd3d1d3bb8096bf6740839dbe@%3Cdev.hbase.apache.org%3E A lot of works have been done to improve the HBCK2 tool so we think it is time to move the stable pointer to 2.x. If no other concerns, 2.2.2 or 2.2.3 will be the next stable version. We discussed the protobuf version for 3.0.0 release. https://lists.apache.org/thread.html/abd60a8985a4898bae03b2c3c51d43a6b83d67c00caff82ba9ab2712@%3Cdev.hbase.apache.org%3E We have moved to a shaded 3.x protobuf version for most code but for CECPs we are still on 2.5.0. This is partly because hadoop is still on 2.5.0. Recently the hadoop community also started to solve the problem, and we will try to help them. There was a discussion on where to place the release scripts: https://lists.apache.org/thread.html/31d44cfd165ff04bed3a74a46311af3c2e857a3a84f08ae0759f2794@<dev.hbase.apache.org> We have several repos now and all of them need to follow the Apache protocols to make releases. We need to find a way to make the release work easier. ## Community Health: - Mailing list activity: dev@hbase.apache.org: 1015 subscribers(1007 in the previous quarter) 1339 emails sent to list(1473 in the previous quarter) user@hbase.apache.org: 2150 subscribers(2171 in the previous quarter) 282 emails sent to list(160 in the previous quarter) - JIRA activity: 455 issues opened in JIRA, past quarter (-5% decrease) 350 issues closed in JIRA, past quarter (-28% decrease) I think after 2.x gets more stable the numbers will keep decreasing, maybe this is a sign that we should start the release for 3.0.0. - GitHub activity: 377 PRs opened on GitHub, past quarter (41% increase) 380 PRs closed on GitHub, past quarter (57% increase) We keep improving the GitHub PR integration and now GitHub PR is the suggested way to submit and review patches. This is why these numbers increasing dramatically.

## Issues:
Board-only information removed from public report.
## Activity:
There have been lots of interesting discussions on the dev@ mailing list.
Highlights:
- HBase 1.2.x is at the end of maintenance (EOM). 1.2.x users are encouraged
to upgrade to the current stable line (1.4.9) or even newer if they are
able.
- We had more discussions of EOLing the 2.0.x line, and decided to release a
2.0.6 release first.

- Toward modularizing HBase code for ease of maintenance and releases, we
created new repositories for hbase-connectors, hbase-native-client,
hbase-filesystem. (https://issues.apache.org/jira/browse/HBASE-20934,

- We improved the Downloads page by removing all references to dist.apache.org
from it. (https://issues.apache.org/jira/browse/HBASE-22206)
- We had several heart-felt discussions, on dev@ and private@, about the
responsibility of the PMC in voting for release candidates, Release Manager
burn-out, the meaning of +0 votes, whether to continue testing a RC after it
is sunk, and other related topics. Some of those discussions are available
to the public.

HBaseCon Asia takes place July 20, 2019, in Beijing. The Call For Papers (CFP)
closed on June 17. (https://hbase.apache.org/hbaseconasia-2019/,

Another goal, spanning several quarters, is to solicit more non-binding votes
on release candidates, as non-binding votes are one signal of broader
community engagement. Based on several discussions, we surfaced the following
further expectations:
- Voting on release candidates is largely about well-formedness of the
artifacts. A script exists to help determine well-formedness.
- A candidate that gets few votes can be discouraging to the release manager
(RM).
- A +0 vote is a powerful signal to the RM that you care about a candidate but
don't have enough information to vote decisively.
- Don't assume a single -1 means a candidate is sunk, even if it looks
serious.
- If you find a problem, file a JIRA and try to help find root cause. Don't
rely on the RM to own every problem.
- PMC members are expected to vote on as many release candidates as possible,
and 1.x releases need more consistent voters. As a reminder, anyone on the
dev@ list can test and provide feedback on a release candidate, and cast a
non-binding vote.
Three new committers were added this quarter, and one committer joined the
PMC. More details below. Thanks to the new committers and PMC members for
agreeing to take on more responsibilities in the project.
## Health report:
We're in the middle of the summer in the northern hemisphere, but it hasn't
slowed down the conversation. Subscribers to dev@ are down a bit (-41), but
discussions are still vigorous, with 1524 emails (1064 last quarter).
The same pattern holds for users@, with 61 fewer subscribers than last
quarter, but 184 emails (115 last quarter).
We're still fixing a lot of JIRAs, and this quarter we fixed ever so slightly
more than we created! Numbers below.

## Description:
Apache HBase is an open-source, distributed, versioned, non-relational
database. Apache HBase gives you low latency random access to billions of rows
with millions of columns atop non-specialized hardware.
hbase-thirdparty is a set of internal artifacts used by the project to
mitigate the impact of our dependency choices on the wider ecosystem.
## Issues:
Board-only information removed from public report.
## Activity:
There have been lots of interesting discussions on the dev@ mailing list.
Highlights:
- We have nearly all the infrastructure ready to complete the move to Gitbox.
(https://lists.apache.org/thread.html/3496568d 6cc002f74f5c3bcce46ed44b7ee9e90d7d53af2c65b6f785@%3Cdev.hbase.apache.org%3E)
- An interesting discussion occurred about the frequency of releases in the
2.1.x line
(https://lists.apache.org/thread.html/222aacbf7 4d9788287ef5606fe66a06c1a3aa31a299a469d124a5ee0@%3Cdev.hbase.apache.org%3E).
The discussion included a sub-discussion about what it will take to separate
the hbck took from the main project, and another sub-discussion about
time-based releases and release cadence in general. It's worth a read.
- A conversation is underway about getting the branch-2 line ready for the
"stable" pointer.
(https://lists.apache.org/thread.html/81b2917e ba3fce2872b96526635a5ba11535c73641cb3d38271ee353@%3Cdev.hbase.apache.org%3E)
- We asked ourselves what our greatest friction point is when attracting new
contributors. We'd love for you to weigh in.

- Sean Busbey, the release manager for 1.2, proposes that 1.2.12 (currently a
release candidate) be the last release in the 1.2 line.
(https://lists.apache.org/thread.html/3cf19458 b739a612fbe1f72d17c14124ff536b0cb8678a63d80cf019@%3Cdev.hbase.apache.org%3E)
Planning is underway for the next HBaseCon Asia! Contact Duo Zhang
<zhangduo@apache.org> to get involved.
The HBase project is working toward the goal of more frequent minor releases
and fewer unprompted maintenance releases. In total this quarter, HBase had 7
releases over this quarter, across 3 release lines, and hbase-thirdparty had 1
release.
Another goal, spanning several quarters, is to solicit more non-binding votes
on release candidates, as non-binding votes are one signal of broader

## Description:
Apache HBase is an open-source, distributed, versioned, non-relational
database. Apache HBase gives you low latency random access to billions of rows
with millions of columns atop non-specialized hardware.
hbase-thirdparty is a set of internal artifacts used by the project to
mitigate the impact of our dependency choices on the wider ecosystem.
## Issues:
## Activity:
There have been lots of interesting discussions on the dev@ mailing list.
Highlights:
- Discussion is ongoing about plans to move to Gitbox and ways the project can
accommodate users who prefer to contribute using Github.
(https://lists.apache.org/thread.html/3496568d 6cc002f74f5c3bcce46ed44b7ee9e90d7d53af2c65b6f785@%3Cdev.hbase.apache.org%3E)
- An interesting discussion occurred about the frequency of releases in the
2.1.x line
(https://lists.apache.org/thread.html/222aacbf7 4d9788287ef5606fe66a06c1a3aa31a299a469d124a5ee0@%3Cdev.hbase.apache.org%3E).
The discussion included a sub-discussion about what it will take to separate
the hbck took from the main project, and another sub-discussion about
time-based releases and release cadence in general. It's worth a read.
- A proposal to retire the 1.3 line resulted in Francis Liu stepping in to be
the release manage for the line, because his team relies on that branch.
Francis is aiming for a quarterly release cadence. In the same discussion,
Andrew Purtell and Sean Busbey discuss how they have been managing 1.2 and
1.4 lines, and plans for the 1.5 line.
(https://lists.apache.org/thread.html/dd655a21 cb5eb23a983648d71f5d08ca567b110ab9128a70f06eddcc@%3Cdev.hbase.apache.org%3E)
- Another discussion of 1.x release cadences was started by Andrew Purtell,
including specific plans for the 1.5 branch.
(https://lists.apache.org/thread.html/e18266c8 aa1e1406f3e652a3a1ee52d498aaad506537621cc754499b@%3Cdev.hbase.apache.org%3E)
- Another interesting discussion resulted in improved understanding and
documentation of the process for editing and rebuilding pages on the HBase
website that don't result from building the documentation.
(https://lists.apache.org/thread.html/18010d08 97752db7f9d91f4f75694831a7ed9db28739ce4a91e546e4@%3Cdev.hbase.apache.org%3E)
- Speaking of 1.5, the first snapshot is available for testing.
(https://lists.apache.org/thread.html/bbf7b479 20da532535bb8ce493df3265fd91211b227f681b2cc3c3a2@%3Cdev.hbase.apache.org%3E)
Josh Elser started a discussion on the PMC list about the definition of and
parameters for an HBaseCon event, who can run one, and other guidelines,
informed by his work organizing HBaseCon US 2018. He's working on some
project-facing documentation, which promises to be helpful for future
organizers of HBase-related events worldwide.
The HBase project is working toward the goal of more frequent minor releases
and fewer unprompted maintenance releases. In total this quarter, HBase had 8
releases over this quarter, across 5 release lines.
Another goal, spanning several quarters, is to solicit more non-binding votes
on release candidates, as non-binding votes are one signal of broader
community engagement. Here are a few examples:
- HBase 1.3.3 RC0 had 40% non-binding votes
(https://lists.apache.org/thread.html/9e3a472e 142faa9a48ed5ab0e1e1baaaeb9ddfe7a9fdcfa547c2cd20@%3Cdev.hbase.apache.org%3E)
- HBase 1.4.8 RC0 had 50% non-binding votes
(https://lists.apache.org/thread.html/2f8ad79f 6da4d2ac223a61b82aeb29a2322479257f271da90f0687e0@%3Cdev.hbase.apache.org%3E)
- HBase 2.1.1 RC0 also had 50% non-binding votes
(https://lists.apache.org/thread.html/f9ccc377 dbeac4b3a7a0cddcef0cd7369675f5b1cc570b6c19a52864@%3Cdev.hbase.apache.org%3E)
As a reminder, anyone on the dev@ list can test and provide feedback on a
release candidate, and cast a non-binding vote.
Lars Hofhansl is in the process of organizing a bay-area HBase developer
meet-up at Salesforce. If you're interested, participate in the thread.

Two new committers were added this quarter, and two committers joined the PMC.
More details below. Thanks to the new committers and PMC members for agreeing
to take on more responsibilities in the project.

HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS. ISSUES FOR THE BOARD'S ATTENTION None at this time. RELEASES We made two releases from our 0.98 code line under the supervision of branch RM Andrew Purtell: 0.98.23 was released on October 22, 2016 and 0.98.24 was released on January 4, 2017. 0.98.24 is expected to be the last regular release from this code line. Andrew Purtell resigned his informal role as long term maintainer and RM for the 0.98 branch a few days ago. We made two releases from our 1.1 code line under the supervision of branch RM Nick Dimiduk: 1.1.7 was released on October 22, 2016 and 1.1.8 was released on December 15, 2016. We made one release from our 1.2 code line under the supervision of branch RM Sean Busbey: 1.2.4 was released on November 6, 2016. Voting on the first release from our 1.3 code line, 1.3.0, under the supervision of branch RM Mikhail Antonov, has almost completed and looks like it will carry. ACTIVITY It is my pleasure to report Stephen Yuan Jiang was added to the PMC on October 13, 2016; and four committers were added since our last report: Lijin Bin joined us on November 17, 2016, Phil Yang joined us on November 26, 2016, Josh Elser joined us on December 10, 2016, and Guanghao Zhang joined us on December 19, 2016.

HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS. ISSUES FOR THE BOARD’S ATTENTION None at this time. RELEASES We made two releases from our 0.98 code line under the supervision of branch RM Andrew Purtell: 0.98.21 was released on August 15, 2016. 0.98.22 was released on September 9, 2016. We made one release from our 1.1 code line under the supervision of branch RM Nick Dimiduk: 1.1.6 was released on September 4, 2016. We made two releases from our 1.2 code line under the supervision of branch RM Sean Busbey: 1.2.2 was released on July 10, 2016. 1.2.3 was released on September 11, 2016. Our upcoming 1.3 code line is in prerelease under the supervision of branch RM Mikhail Antonov, now taking on production-like workloads to shake out the handful of remaining issues. Recently the community updated plans for branching for the next major code line, 2.0. Co-RMs Matteo Bertozzi and Stephen Yuan Jiang will supervise. (Because of his volunteerism in this regard, discussion is underway to add Stephen Yuan Jiang to the PMC.) In broad strokes the plan is to branch and produce an alpha quality preview some time in November of 2016, then stabilize toward beta quality by the end of this calendar year. ACTIVITY It is my pleasure to report the project added four new PMC during this reporting period. Dima Spivak was added to the PMC on August 30, 2016. Duo Zhang joined us on September 5, 2016. Misty Stanley-Jones joined us on September 6, 2016. Stephen Yuan Jiang joined us on October 14, 2016. Dima Spivak was granted committer and PMC status simultaneously, increasing the ranks of our committers by one, to 53. We had enough interest in HBaseCon, the yearly conference for the HBase community that took place earlier this year in May, that the Program Committee had to turn away quality talk proposals. Thanks to generous contribution of hosting space and logistics from Google and Bloomberg we found a home for this overflow in an additional East Coast edition[1] which took place last month and was well attended by members of our user and developer communities. The organizers of the HBase-NYC meetup group report that their membership went from ~600 pre-event to ~850 post, showing a good increase in local community interest. STATS Mailing list membership has been steady. The JIRA open/close rate and ratio is very close to that reported last time. 53 committers 31 PMC 1066 subscribers to the dev list (up 3 in the last 3 months) 2355 subscribers to the user list (up 5 in the last 3 months) 592 JIRA tickets created in the last 3 months 457 JIRA tickets closed/resolved in the last 3 months 1. http://www.meetup.com/HBase-NYC/events/233024937/
HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS. ISSUES FOR THE BOARD’S ATTENTION None at this time. RELEASES Despite my personal concerns about available community bandwidth for maintaining several code lines, we are holding steady with three released code lines (0.98, 1.1, and 1.2) plus development activity on the next minor increment (1.3), the parent of the 1.x release series (branch-1) and the project trunk (master, aka 2.0). We have one committer allocated as release manager for each code line to supervise (except branch-1). Committers are largely maintaining the discipline of committing changes first to master then back through all active branches according to our documented source and binary change compatibility policy. An exception is 0.98. For this "long term stable" code line the branch RM has volunteered responsibility for porting back all desired changes committed to later code lines. We made two releases from our 0.98 code line: 0.98.19 was released on April 28, 2016; and 0.98.20 was released on June 12, 2016. We made one release from our 1.1 code line: 1.1.5 was released on May 12, 2016. We made one release from our 1.2 code line: 1.2.1 was released on April 5, 2016. Work to complete the first release from our 1.3 code line is ongoing and should be completed soon. The 1.3 code line will be managed by our newest PMC member, Mikhail Antonov. Once 1.3.0 is released I expect we will have a discussion on dropping active maintenance of an older code line to compensate. ACTIVITY Mikhail Antonov was added to the PMC on May 23, 2016. We added two committers over this reporting interval. Apekshit (Appy) Sharma joined us on June 3, 2016 and Jingcheng Du joined us on June 16, 2016. HBaseCon, the yearly conference for the HBase community, took place on Tuesday, May 24, 2016 at The Village on Market Street in San Francisco, and was attended by several hundred members of our user and developer communities.

ISSUES FOR THE BOARD’s ATTENTION
In our last report, we wrote of how the HBase PMC had gotten no
response to petitions requesting that MapR Technologies fix
conflation of Apache HBase with their MapR M7 product ("Making
HBase™ Enterprise Grade"). After a new set of violations were
raised on trademarks@ on May 3rd [1], Shane wrote them on
May 17th[2]. He got a response. Since this exchange,
there has been a marked change in how they market their MapR
M7 product; now they talk of it as being a "nosql" store.
Offending text remains[3] but is minor relative to what was
there previous.

HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’S ATTENTION Following on from our last report where we raised the issue of MapR Technologies conflating Apache HBase and their M7 offering, we have had no response from MapR to our letter of January 9th -- we just sent them a ping -- and to my untrained eye, their website continues in violation [1]. RELEASES 0.94.5 -- 02/15/2013 0.94.6 -- 03/22/2013 0.94.6.1 which replaces 0.94.6 -- 04/07/2013* 0.95.0, the first in a "Development" Series[3] of releases that preview the coming 0.96.0 -- 04/07/2013 COMMITTERS We added the following new committers over this period: Amitanand Aiyer (Facebook) -- acube123@apache.org Anoop Sam John (Intel, was Huawei at time of vote) -- anoopsamjohn@apache.org Sergey Shelukhin (HortonWorks) -- sershe@apache.org PMC We added the following PMC members over this report's period: Jimmy Xiang -- jxiang@apache.org Nicolas Liochon -- nkeywal@apache.org COMMUNITY Contribution rate is healthy.

HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’s ATTENTION MapR Technologies released MapR M7 Edition on 10/23/2012. Their website and supporting materials for the M7 product claim, "Making HBase Easy, Dependable, and Fast", and making "HBase Enterprise Grade" though their product is not HBase. The HBase PMC, with the help of trademarks@, wrote MapR on 10/31/2011 asking them to make proper Apache attribution (They referred to HBase, not Apache HBase), to note our Apache trademark, and to make clearer the distinction between their M7 product and HBase on their website and in their marketing materials. They have since made changes to their website adding our Apache prefix and trademark but have yet to address the larger conflation of M7 and "HBase" issue. We sent them a second letter on January 9th (after letting the text stew a week on trademarks@). RELEASES 0.94.3 on December 3rd, 2012 0.94.4RC0 was put up on January 3rd, 2013 COMMITTERS We added: Jesse Yates (SalesForce) -- jyates@apache.org Matteo Bertozzi (Cloudera) -- mbertozzi@apache.org Chunhui Shen (TaoBao) -- zjushch@apache.org COMMUNITY We had a bug squashing meetup at Cloudera in San Francisco on December 4th [1], a user group meeting at Wize Commerce in San Mateo on October 29th [2], and there was a user group meetup in NYC on October 25th at AppNexus [3]. 26 committers [4] (Was 23 in last report) 833 subscribers to the dev list (Was 800 at last report) 1896 subscribers to the user list (Was 1833 at last report) 1. http://www.meetup.com/hackathon/events/90536432/ 2. http://www.meetup.com/hbaseusergroup/events/82791572/ 3. http://www.meetup.com/HBase-NYC/events/81728932/

HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’s ATTENTION None. RELEASES 0.94.1 on August 8th. 0.94.2 is on its fourth release candidate. 0.92.2 on October 1st. COMMITTERS We added: Gregory Chanan (Cloudera) -- gchanan@apache.org Enis Soztutar (Hortonworks) -- enis@apache.org Elliott Clark (Was StumbleUpon when elected, now Cloudera) -- eclark@apache.org COMMUNITY Contributors met at Hortonworks for a pow wow on September 11th, 2012 [1]. Notes and pointers to talks posted here [2]. After discussion up on the dev list, we introduced the notion of an 'owner' role. "Owners are volunteers who are (usually, but not necessarily) expert in a component domain and may have an agenda on how they think their HBase component should evolve." Owners will try and review patches that fall within their domain and if an agenda will publish it. See [3] for more. 23 committers [4] (Was 20 in last report) 800 subscribers to the dev list (Was 759 at last report) 1833 subscribers to the user list (Was 1734 at last report) 1. http://www.meetup.com/hbaseusergroup/events/80621872/ 2. http://search-hadoop.com/m/OXGqy1dlFAE1 3. http://hbase.apache.org/book.html#OWNER 4. http://hbase.apache.org/team-list.html
The "owner" term is problematic, and might be misinterpreted. AI: Brett follow up with PMC to clarify the "owner" role.
HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’s ATTENTION None. RELEASES 0.94.0, a major release, on May 2nd. A release candidate for 0.92.2 was posted and retracted with another candidate to follow. 0.94.1 and 0.90.7 release candidates should be going up in the next week or so. COMMITTERS We changed our policy where a committer automatically was also made a member of the PMC. Now you become a committer first and then after a period, you are invited by the PMC to become a member. The general consensus was that such a policy would lower the barrier minting new hbase committers [1]. Nicolas Liochon (Scaled Risk) -- nkeywal@apache.org Jimmy Xiang (Cloudera) -- jxiang@apache.org Liyin Tang (Facebook) -- liyin@apache.com Nicolas and Jimmy are committers only. Liyin was the last to make it as a committer+PMC member before the policy change. COMMUNITY We had our first hbase conference on May 22nd in San Francisco, hbasecon [2]. It seems to have gone over well (600 attendees). A Birds-of-a-feather session on the day after the hadoop summit was less well attended, ~30 [3]. 20 committers [4] (Was 17 in last report) 759 subscribers to the dev list (Was 703 at last report) 1734 subscribers to the user list (Was 1632 at last report) 1. https://mail-search.apache.org/members/private-arch/hbase-private/201205.mbox/%3CCADcMMgHy+TdZyefkruAQog1n8CEY6ajrf=sTh1wR4J+dtEKHFg@mail.gmail.com%3E 2. http://hbasecon.com 3. http://www.meetup.com/hbaseusergroup/events/59829652/ 4. http://hbase.apache.org/team-list.html

HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’s ATTENTION None RELEASES 0.90.6, a point release with 38 fixes over 0.90.5. 0.92.0 was released January 23rd. 0.92.1 was released March 17th with 64 fixes over 0.92.0. The first release candidate for 0.94.0, our next major release, was put up on March 27th. COMMITTERS We added one new committer (and PMC member): Mikhail Bautin (Facebook) -- mbautin@apache.org COMMUNITY We had a meetup on March 27, 2012 in San Francisco [1]. Beforehand, a majority of PMC members met to discuss face to face hbase project issues. The agenda and minutes were posted on our blog and to the mailing list [2].

There appears to be a discrepancy in the url for the hackathon. AI Brett: follow up with PMC and update minutes.
HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’s ATTENTION In the HBase project, folks who have been made committers automatically become members of the HBase PMC only I failed to ask the boards' permission adding new PMC members. The current list of committers who are also members of the PMC can be found here: http://hbase.apache.org/team-list.html I will follow the protocol going forward requesting ACK and waiting 72 hours before adding new PMC members. Is there anything I should do about my past failing in this regard? RELEASES No new releases. Developer focus is (still) on stabilizing 0.92.0, our next major release COMMITTERS We added two new committers during this period: Ramkrishna S Vasudevan and Lars Hofhansl COMMUNITY The HBase O'Reilly book was released We have a new logo. Developer velocity has picked up over the last month. We had a well attended meetup, ~130 people, at Facebook on 22nd of August [1] It was preceded by a hackathon attended by ~30 people. 639 subscribers to the dev list 1421 subscribers to the user list St.Ack 1. http://www.meetup.com/hbaseusergroup/events/28518471/ 2. http://www.meetup.com/hackathon/events/28754491/
Several PMC members apparently have not been ACK'd by the board.
AI Roy: request PMC chair send list of PMC members that have not been ACK'd so they can be properly approved
HBase status report, August 2011 HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD’s ATTENTION None at this time. RELEASES 0.90.4 should be out by the time the board reads this report Developer focus is on stabilizing up 0.92.0, our next major release. COMMITTERS We added two new committers during this period: Ted Yu and Doug Meil. COMMUNITY We had a well attended meetup, ~70 people, at Yahoo on the day after the Hadoop Summit [1]. Our next hackathon+meetup is on the 22nd [2]. 586 subscribers to the dev list 1359 subscribers to the user list 129 subscribers to the issues list St.Ack 1. http://www.meetup.com/hbaseusergroup/events/20572251/ 2. http://www.meetup.com/hbaseusergroup/events/28518471/
Report missing; will report next month.
HBase status report, April 2011 HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD'S ATTENTION None at this time. RELEASES We released 0.90.0 in January, 0.90.1 in February, and last week, we released 0.90.2. Developer focus is now mostly on getting 0.92.0 out. COMMITTERS No new committers during this period. COMMUNITY We had a well attended meetup in February [1] and an open hackathon in March [2] User mail has about doubled over same period last year. 511 subscribers to the dev list 1217 subscribers to the user list 97 subscribers to the issues list 1. http://www.meetup.com/hbaseusergroup/events/16492913/ 2. http://www.meetup.com/hackathon/events/16770852/
HBase is a distributed column-oriented database built on top of Hadoop Common and Hadoop HDFS ISSUES FOR THE BOARD's ATTENTION None at this time. RELEASES We have made four release candidates for 0.90.0 since our last report where HBase 0.90.0 is the next major HBase release to follow 0.20.0 (For more on the odd looking HBase versioning, see [1] below). COMMITTERS We added two new committers during this period. Gary Helmling has been a long-time contributor and works for Trend Micro. Nicolas Spiegelberg is at Facebook and has made many and substantial contributions to both HBase and HDFS over the last year or so. Our PMC voted to make committers == PMC members. All committers that were not yet PMC members were promoted. COMMUNITY Big news this period was the announcement by Facebook that their Messaging will be built on top of HBase (For example, [2]). Facebook have been making many substantial contributions to HBase over the last year or so. Mailing list traffic in user is about constant with this period last year -- ~500 mesages per month -- with spikes in September and December where our traffic doubled over last years numbers (Its hard to compare dev mailing list since it used conflate issues and dev traffic since fixed). We had a successful open hackathon at Facebook on December 13th, 2010 attended by about 30 or so folks.

ISSUES FOR THE BOARD'S ATTENTION None at this time. RELEASES We made three releases over this period: a new patch release of our 0.20 branch -- this is our current 'stable' offering -- and two 'developer releases' from TRUNK named 0.89.DATE_OF_RELEASE (See [1] for more on what our 'developer releases' are): * July 30th, 2010: HBase 0.20.6 released * August 9th, 2010: HBase 0.89.20100726 * October 5th, 2010: HBase 0.89.20100924 TRUNK is currently under feature freeze as we stabilize before cutting a 0.90.0 release candidate in the next week or so (0.90.0 will be the version of our next major release [1]). COMMITTERS We added no new committers this period. We proposed a contributor who has made > 20 quality patches but he declined our offer. COMMUNITY HBase had a respectable showing at Hadoop World, October 12th [2]. The night before we held our first NYC user group meeting which was well attended [3]. Mailing list traffic is about constant with this period last year in the user mailing list, though September traffic was up by about 50% over last year. Our Google Summer of Code student completed his 'table snapshot' assignment -- hbase-50 -- though it is yet to be committed. There has been healthy debate up on the mailing lists around what will be included/excluded in our next major release. 1. http://wiki.apache.org/hadoop/Hbase/HBaseVersions 2. http://hbaseblog.com/2010/10/14/hbaseworldnyc2010/ 3. http://www.meetup.com/hbaseusergroup/calendar/14606174/
What is meant by a "developer release". Apache releases software without stipulation for its intended audience.
AI Greg: follow up to clarify the "developer release" term.
HBase is a distributed column-oriented database built on top of Hadoop Common and HDFS On June 30th, the day after the hadoop summit, Facebook hosted an hbase 'summit' that was well attended [1]. Releases: * We released hbase-0.20.5 June 24th. It had 24 fixes over 0.20.4 * We released 0.89.20100621, a stabilized preview/beta of the next major version of hbase, cut from TRUNK, on June 25th Next week we will put up two new release candidates: one for 0.20.6 and another release in the 0.89.x series. Development is brisk on TRUNK as we head toward our next major version release, hbase-0.90.0. (To learn about why the jump in hbase versioning -- from 0.20.x to 0.89.x and 0.90.x for our next release, see [2]). No new committers added in this period. 1. http://www.meetup.com/hbaseusergroup/calendar/13562846/ 2. http://wiki.apache.org/hadoop/Hbase/HBaseVersions
