It offers high-level APIs in Java, Scala, Python and R as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: - We released Spark 2.1.2 on October 9th, with maintenance fixes for the 2.1 branch. This release was also managed by a new committer, which helped expose issues in the release process documentation that we've fixed. We are encouraging more new committers to be RMs for upcoming releases like 2.2.1. - The Spark Summit Europe conference ran in Dublin, Ireland in October with 1200 attendees. - Work is under way to merge Kubernetes support for Spark 2.3.0, with the first major pull requisition having undergone a bunch of review and getting close to merging. We need one more pull request beyond this for basic support. SPIPs: We wanted to give an update on Spark Project Improvement Proposals (SPIPs), the process we started to formally propose large changes before having an implementation. Since we started the process, there have been seven SPIPs proposed on the mailing list with the first in June 2017, which are all listed in JIRA at https://s.apache.org/aMHI. So far all the voted-on SPIPs have been accepted and it seems that the discussions, both on our dev list and in JIRA, have been useful, resulting in design changes, better understanding of each idea, and feedback from a wide range of Spark users. Some of the major SPIPs discussed and accepted include Kubernetes support, images as a first-class data type in MLlib, updates to the data source API, and low latency continuous processing. We will continue to encourage people to write large proposals as SPIPs to generate this type of discussion. Trademarks: - No large issues to report in the past 3 months.

Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala, Python and R as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: - The community released Apache Spark 2.0.1 on October 3rd, 2016 as the first patch release for the 2.x branch. We also released Spark 1.6.3 on November 7th to continue patching the 1.x branch, and started voting on release candidates for Spark 2.0.2 with more patches to 2.x. - The Spark Summit Europe conference ran in Brussels on Oct 25-27 with around 1000 attendees, including presentations on new use cases at Microsoft and Facebook. - There've been several discussions on the dev list about making the development process easier to follow and giving feedback to contributors faster. One concrete thing we'd like to implement is a process to post "improvement proposals" scoping a new feature before detailed design begins, so that developers can solicit feedback from users earlier, and users can easily see the project's high-level roadmap in one place. The most recent writeup on this is at https://s.apache.org/ndAX and seems to be welcomed by contributors who've used a similar process in other ASF projects. Other things that contributors are working on are creating a template for design documents and cleaning up JIRA. Trademarks: - We are continuing engagement with various organizations.

Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala, Python and R as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: - The community is continuing to make progress towards its 2.0 release, with two release candidates having been posted. Apache Spark 2.0 is a major release that includes a new SQL-based high-level streaming API, machine learning model persistence, and cleanup of Spark's dependencies and internal APIs. The full list of changes in Apache Spark 2.0 is available at http://s.apache.org/spark-2.0-features. - We released Spark 1.6.2 on June 26th, with bug fixes for the 1.6 branch of the project (https://s.apache.org/spark-1.6.2). Trademarks: - The PMC is engaging with several third parties that are using Spark in product names, branding, etc. - The PMC has been working on a page about trademark guidelines to include on the Spark website (https://s.apache.org/PaXo). It would be great to get feedback on this (several board members said it was a good idea to create such a page after we suggested it in our last report). - To make the project's association with the ASF clearer in news articles and corporate materials, we have updated its logo to include "Apache": https://s.apache.org/Jf7J. This change is live on the website, JIRA, etc. Latest releases: June 25, 2016: Spark 1.6.2 May 26, 2016: Spark 2.0.0-preview Mar 9, 2016: Spark 1.6.1 Jan 4, 2016: Spark 1.6.0 Nov 09, 2015: Spark 1.5.2 Committers and PMC: The last committer was added on May 23, 2016 (Yanbo Liang).

Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala, Python and R as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: - The community is in the QA phase for Spark 2.0, our second major version since joining Apache. There are a large number of additions in 2.0, including a higher-level streaming API, improved runtime code generation for SQL, and improved export for machine learning models. We are also using this release to clean up some experimental APIs, remove some dependencies, add support for Scala 2.12. The full list of changes is available at http://s.apache.org/spark-2.0-features. We also released a 2.0.0-preview package to let users broadly participate in testing the new APIs. - We released Spark 1.6.1 in March, with bug fixes for the 1.6 branch. - For Apache Spark 2.0, the community decided to move some of the less used data source connectors for Spark Streaming to a separate project, Apache Bahir (http://bahir.apache.org). We proposed a new project in order to maintain ASF governance of these components. - The project removed the role of "maintainers" for reviewing changes to specific components (originally added 1.5 years ago) in response to concerns from some ASF members that it makes the project appear less welcoming, as well as the conclusion that it did not have a noticeable impact in practice (https://s.apache.org/DUTB, https://s.apache.org/AgCt). Trademarks: In the past few weeks, there have been several discussions asking for more attention to trademark use from the PMC. Some of the main issues were: - A vendor offering a "technical preview" package of Apache Spark 2.0 before there was any official PMC release. - A vendor claiming to offer "early access" to the project's roadmap. - Various corporate and open source products whose name includes "Spark". - Corporate pages were the most prominent mention says "Spark" instead of "Apache Spark". The PMC is addressing these issues in several ways: - Reaching out to the organizations involved. - To make the project's association with the ASF clearer in news articles and corporate materials, we are working to update the logo to include "Apache": https://s.apache.org/Jf7J. We also added a FAQ entry about using the logo that links to the ASF trademarks page. - Continuing to review news articles, product announcements, etc. - Starting with this board report, we will have a section on trademarks in our reports to track brand activity. - Question for the board: Would it be helpful to put a summary of the trademark policy on spark.apache.org? It would be nice to have this more visible (e.g. in the site's navigation menu), but either way is fine. We can draft a version and sent it to trademarks@. Events: - The Spark Summit community conference in San Francisco ran June 6-8. There were close to 100 talks from at least 50 organizations. Latest releases: - May 26, 2016: Spark 2.0.0-preview - Mar 9, 2016: Spark 1.6.1 - Jan 4, 2016: Spark 1.6.0 - Nov 09, 2015: Spark 1.5.2 - Oct 02, 2015: Spark 1.5.1 Committers and PMC: - The last committer was added on May 23, 2016 (Yanbo Liang). - The last PMC members were added Feb 15, 2016 (Joseph Bradley, Sean Owen and Yin Huai)

Project status:
- The community is entering the QA phase for Spark 2.0, our second major
version since joining Apache. There are a large number of additions in
2.0, including a higher-level streaming API, improved runtime code
generation for SQL, and improved export for machine learning models.
We are also using this release to clean up some experimental APIs,
remove some dependencies, add support for Scala 2.12. The full list
of changes is available at http://s.apache.org/spark-2.0-features.
- We released Spark 1.6.1 in March, with bug fixes for the 1.6 branch.
In general, we have seen fast adoption of Spark 1.6, with many
organizations adding support right away.
- For Apache Spark 2.0, the community decided to move some of the lesser
used data source connectors for Spark Streaming to a separate ASF
project, which has been proposed as Apache Bahir. We proposed a new
project in order to maintain ASF governance of these components.
- In the past few weeks, there have been several discussions asking
for more attention to trademark use from this PMC. Some of the main
issues were:
- A vendor offering a "technical preview" package of Apache Spark 2.0
before there was any official PMC release.
- A vendor claiming to offer "early access" to the project's roadmap.
- Multiple vendors offering products were one component is labeled
"Spark", without this component being an ASF release.
- Corporate pages were the most prominent mention says "Spark"
instead of "Apache Spark".
In response to these issues, we will be reviewing all corporate uses
of "Spark" on the trademarks list in the coming weeks and working to
clarify the trademark rules on the project website as well as within
the PMC and committer community.

Shane wants Spark to take ownership of the trademark issues; and for individuals on the PMC who work for companies in this space to ensure that their companies are exemplars. Trademarks won't engage until there is some evidence that there is a reasonable attempt made by the PMC.
Jim thanked Matei for attending, and outlined possible future actions the board might take if these concerns are not addressed.

Some features coming there include a data frame API similar to R and Python, write support for external data sources, and quite a few new machine learning algorithms. - We had a discussion about adding a committer role to the project that is separate from PMC (before, Spark had PMC = C) to bring in people sooner, and decided to do that from this point on. Releases: Our last few releases were: February 9, 2015: Spark 1.2.1 December 18, 2014: Spark 1.2.0 November 26, 2014: Spark 1.1.1 September 11, 2014: Spark 1.1.0 Committers and PMC: The last committers were added February 2nd, 2015 (Joseph Bradley, Cheng Lian and Sean Owen) The last PMC members were added August 12th, 2014 (Joseph Gonzalez and Andrew Or).
Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala, and Python as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: This has been an eventful three months for Spark. Some major happenings are: - We posted our 1.1.0 release in September, with contributions from 171 developers (our largest number yet). Major features were performance and scalability optimizations, JSON import and schema inference in Spark SQL, feature extraction and statistics libraries, and a JDBC server. - We recently cut a release branch and started QA for Spark 1.2.0, which is targeted for release in December. - Apache Spark won this year's large-scale sort benchmark (http://sortbenchmark.org/), sorting 100 TB of data 3x faster than the previous record. It tied with a MapReduce-like system optimized for sorting. - The community voted to implement a maintainer model for reviewing some modules, where changes in architecture and API should be reviewed by a maintainer before a merge (http://s.apache.org/Dqz). There was concern from some external commenters (Greg Stein, Arun Murthy, Vinod Vavilapalli) that this reduces the power of each PMC member (requiring a review from a specific set of people); we are looking to test how this works and possibly tweak the model. Releases: Our last few releases were: September 11, 2014: Spark 1.1.0 August 5, 2014: Spark 1.0.2 July 23, 2014: Spark 0.9.2 July 11, 2014: Spark 1.0.1 Committers and PMC: The last committers and PMC members were added August 12, 2014 (Joseph Gonzalez and Andrew Or).
Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala, and Python as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: Spark made its 1.0.0 release on May 30th, bringing API stability for the 1.X line and a variety of new features. The community is now QAing the 1.1.0 branch for release later this month. (We follow a regular 3-month schedule for releases.) The community held a user conference, Spark Summit, in July, sponsored by 25 companies. We continue to see growth in the number of users and contributors, with over 120 people contributing to 1.1.0. Some of the big features in 1.1 include JSON loading in Spark SQL, a new statistics library, streaming machine learning algorithms, improvements to the Python API, and many stability and performance improvements. Releases: Our last few releases were: August 5, 2014: Spark 1.0.2 July 23, 2014: Spark 0.9.2 July 11, 2014: Spark 1.0.1 May 30, 2014: Spark 1.0.0 Committers and PMC: We closed votes to add two new committers and PMC members on August 7th. Before that, we added two committers and PMC members in May 2014.
Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala and Python as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: The project is closing out the work for its 1.0.0 release, which will be a major milestone introducing both new functionality and API compatibility guarantees across the 1.X series. We’ve had one release candidate posted and are working on the next after a period of heavy QA. The project continues to see fast community growth — over 100 people submitted patches for 1.0. Some of the major features in 1.0 include: - A new Spark SQL component for accessing structured data within Spark programs - Java 8 lambda syntax support to make Spark programming in Java easier - Sparse data support, model evaluation, matrix algorithms and decision trees in MLlib - Long-lived monitoring dashboard - Common job submission script for all cluster managers - Revamped docs including new detailed docs for all the ML algorithms - Full integration with Hadoop YARN security model - API stability across the entire 1.X line Releases: Our last few releases were: Apr 9, 2014: Spark 0.9.1 Feb 2, 2014: Spark 0.9.0-incubating Dec 19, 2013: Spark 0.8.1-incubating Sept 25, 2013: Spark 0.8.0-incubating Committers and PMC: We just opened votes for two new committers and PMC members on May 12th. The last committers and (podling) PMC members were added on Dec 22, 2013
Apache Spark is a fast and general engine for large-scale data processing. It offers high-level APIs in Java, Scala and Python as well as a rich set of libraries including stream processing, machine learning, and graph analytics. Project status: --------------- The project recently became a TLP and continues to grow in terms of community size. We finished switching our infrastructure to spark.apache.org, including recently importing our JIRA instance. We completed the vote on a 0.9.1 minor release last week (it will be posted on April 9th), and we reached the feature freeze and QA point for our 1.0 release, which is coming in a few weeks. Apart from the new features coming in 1.0, a major update in the community has been a change towards a Semantic Versioning-like policy, where maintenance releases are clearly marked and API compatibility is preserved across all minor releases (i.e. all 1.x.y will be compatible). This has been put in action for both 0.9.x and 1.x. Releases: --------- Our last few releases were: Apr 9, 2014: Spark 0.9.1 Feb 2, 2014: Spark 0.9.0-incubating Dec 19, 2013: Spark 0.8.1-incubating Sept 25, 2013: Spark 0.8.0-incubating Committers and PMC: ------------------- The last committers and (podling) PMC members were added on Dec 22, 2013.

Project status: The project recently became a TLP and continues to grow in terms of community size. We switched all our infrastructure out of the incubator and to spark.apache.org domains / repos (though the old site still needs a redirect). We have a new minor release being finalized for later this month, and a Spark 1.0 release targeting end of April. Recent activity includes new machine learning algorithms, updating the Spark Java API to work with Java 8 lambda syntax, Python API extensions, and improved support for Hadoop YARN.

Spark is an open source system for fast and flexible large-scale data
analysis. Spark provides a general purpose runtime that supports
low-latency execution in several forms.
Spark has been incubating since 2013-06-19.
Three most important issues to address in the move towards graduation:
1. Pretty much the only issue remaining is importing our old JIRA
into Apache (https://issues.apache.org/jira/browse/INFRA-6419).
Unfortunately, although we've been trying to do this since June,
we haven't had much luck with it, as the INFRA people who tried
to help out have been busy and software version numbers have
often been incompatible (we have a hosted JIRA instance from
Atlassian that they regularly update). We believe that there are
some export dumps on that issue that are compatible with the ASF's
current JIRA version, but if we can't get this resolved in the
next 2-3 weeks, we may simply forgo importing our old issues.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
It would be really great to get a contact who can sit down with us
and do the JIRA import. We're not sure who from INFRA leads these
tasks.
How has the community developed since the last report?
We made a Spark 0.8.1 release in December, and are working on a new
major release (0.9) this month. We added two new committers, Aaron
Davidson and Kay Ousterhout.
How has the project developed since the last report?
We made the Spark 0.8.1 release mentioned above, with a number of
new features detailed at
http://spark.incubator.apache.org/releases/spark-release-0-8-1.html.
We also have some exciting features coming up in Spark 0.9, such as
support for Scala 2.10, parallel machine learning libraries in
Python, and improvements to Spark Streaming.

Shepherd/Mentor notes:
Alan Cabrera (acabrera):
Seems like a nice active project. IMO, there's no need to wait import
to JIRA to graduate. Seems like they can graduate now.

Three most important issues to address in the move towards graduation:
1. Move JIRA over to Apache (still haven't gotten success from INFRA
on this: https://issues.apache.org/jira/browse/INFRA-6419)
2. Add more committers under Apache process
3. Make further Apache releases
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
We still need some help importing our JIRA -- see INFRA-6419. For some
reason we've had a lot of trouble with this. It should be easier now
because Apache's JIRA was updated and now matches our version.
How has the community developed since the last report?
We made the Spark 0.8.0 release, which was the biggest so far, with 67
developers from 24 organizations contributing. The release shows how far
our community has grown -- our 0.6 release last October had only 17
contributors, and our 0.7 release in February had 31. Most of the
contributors are now external to the original UC Berkeley team.
How has the project developed since the last report?
We made the Spark 0.8.0 release mentioned above, which so far seems to
be doing well. It brings a number of deployability features, improved
Python support, and a new standard library for machine learning; see
http://spark.incubator.apache.org/releases/spark-release-0-8-0.html
for what's new in the release.

Move development to Apache repo (in progress) Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of? We still need some help importing our JIRA, though Michael Joyce and INFRA have looked into it (see <http://s.apache.org/fi>). How has the community developed since the last report? We're continuing to get a lot of great contributions to Spark. UC Berkeley also recently hosted a two-day training on Spark and related technologies (http://ampcamp.berkeley.edu/3/) that was highly attended -- we sold out at over 200 on-site attendees, and had 1000+ people watch online. User meetups included a well-attended meetup on Shark (Hive on Spark) contributions at Yahoo!. How has the project developed since the last report? We've made a lot of progress towards a first Apache release of Spark, including changing the package name to org.apache.spark, documenting the third-party licenses as required in LICENSE / NOTICE, and updating the documentation to reflect the transition. This month we've also moved our website to an apache.org domain (http://spark.incubator.apache.org) and updated the branding there. Finally, on the code side, we have continued to make bug fixes and improvements for the 0.8 release. Some recently merged improvements include simplified packaging and Python API support for Windows.

Three most important issues to address in the move towards graduation:
1. Finish bringing up Apache infrastructure (the only system missing
is JIRA, but we also still need to move out website to Apache)
2. Switch development to work directly against Apache repo
3. Make a Spark 0.8 release through the Apache process
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
Nothing major. We've gotten a lot of help setting up infrastructure and the
last piece missing is importing issues from our old JIRA, which we're
working with INFRA on (https://issues.apache.org/jira/browse/INFRA-6419).
How has the community developed since the last report?
We've continued to get and accept a number of external contributions,
including metrics infrastructure, improved web UI, several optimizations and
bug fixes. We held a meetup on machine learning on Spark in San Francisco
that got around 200 attendees. Finally, we've set up Apache mailing lists
and warned users of the migration, which will complete at the beginning of
September.
How has the project developed since the last report?
We are finishing some bug fixes and merges to do a first Apache release of
Spark later this month. During this release we'll go through the process of
checking that the right license headers are in place, NOTICE file is
present, etc, and we'll complete a website on Apache.
Date of last release:
None yet.

2. Migrate mailing lists and development to Apache
3. Make a Spark 0.8 under the Apache Incubator
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware
of?
While most of our infrastructure is now up, it has taken a while to get a
JIRA, a SVN repo for our website (so we can use the CMS), and a
user@spark.incubator.apache.org mailing list (so we can move our existing
user list, which is large).
How has the community developed since the last report?
We only entered the Apache Incubator at the end of June, but in the existing
developer community keeps expanding and we are seeing many new features from
new contributors.
How has the project developed since the last report?
In terms of the Apache incubation process, we filed our IP papers and got a
decent part of the infrastructure set up (Git, dev list, wiki, Jenkins
group).
