Community-led development "The Apache Way"
This was extracted (@ 2020-12-16 21:10) from a list of minutes
which have been approved by the Board.
Please Note
The Board typically approves the minutes of the previous meeting at the
beginning of every Board meeting; therefore, the list below does not
normally contain details from the minutes of the most recent Board meeting.
Meeting times vary, the exact schedule is available to ASF Members and Officers, search for "calendar" in the Foundation's private index page (svn:foundation/private-index.html).
Report was filed, but display is awaiting the approval of the Board minutes.
Livy is web service that exposes a REST interface for managing long running
Apache Spark contexts in your cluster. With Livy, new applications can be
built on top of Apache Spark that require fine grained interaction with many
Spark contexts.
Livy has been incubating since 2017-06-05.
### Three most important unfinished issues to address before graduating:
1. Start preparing towards graduation
2.
3.
### Are there any issues that the IPMC or ASF Board need to be aware of?
None
### How has the community developed since the last report?
Moderate activity on mailing lists and code as well
### How has the project developed since the last report?
Currently the community is working on HA
feature and support for Spark on Kubernetes.
Spark 3.0 support was added recently and a new release
will be started once it has been more thought tested

### Three most important unfinished issues to address before graduating:
1. Grow the community to get more reviews and content.
However, at this point, the community might want to consider that it
is a stable project that has met its initial functional goals. With
multiple public releases under its belt, it might be worth discussing a
time to graduate. A substantial increase in community activity in terms of
code contribution and related community growth might occur after a new set
of functionality/scope is identified for the project. But to date, the
existing community and code are following the Apache way.

Livy thrift JDBC part is GA now. Currently the community is working on HA
feature. And 0.7.0 release is ongoing.

How has the community developed since the last report?
The user email list has kept a consistent flow of discussion around the project.
How has the project developed since the last report?
Version 0.6 was released
How would you assess the podling's maturity?
Mailing lists and project development follow the Apache way.
The user community is active but lately the rate of change in the project
code is lower.
This may not be a cause for concern since it might indicate relative
maturity in achieving the desired functionality of the project.
