Incubator PMC report for March 2016

The Apache Incubator is the entry path into the ASF for projects and
codebases wishing to become part of the Foundation's efforts.

There are 52 podlings currently undergoing incubation.

* Community

  New IPMC members:

  - Kathey Marsden
  - Daniel John Debrunner

* New Podlings

  - Guacamole
  - Joshua
  - Quarks

* Graduations

  The board has motions for the following:

  - Sentry

* Releases

  The following releases entered distribution during the month of
  February:

  2016-02-06 Apache Geode 1.0.0-incubating.M1
  2016-02-07 Apache Apex v3.3.0-incubating
  2016-02-11 Apache Wave 0.4.0-incubating
  2016-02-11 Apache SystemML 0.9.0-incubating
  2016-02-11 Apache TinkerPop 3.1.1-incubating
  2016-02-20 Apache Johnzon 0.9.3-incubating
  2016-02-25 Apache Kudu (incubating) 0.7.0
  2016-02-26 Apache AsterixDB 0.8.8-incubating

* IP Clearance

  - No podling related IP Clearances were processed during this time.

* Legal / Trademarks

  - There was substantial discussion on general@incubator about how
    challenging it is to produce compliant LICENSE and NOTICE files.

  - A couple of podlings with runtime LGPL dependencies pledged to remove
    those dependencies before graduation but were permitted to make
    incubating releases in the meantime.  There was uncertainty as to
    whether VP Legal's approval was required; ultimately VP Legal appeared
    on general@incubator and approved the plans.

* Infrastructure

  - The Freemarker podling had a long standing request to use their existing
    domain as the primary domain.  This was approved by Shane Curcuru but
    closed by infra without comment, see INFRA-10787.

  - The Kudu podling is currently running its website as http://getkudu.io.
    The standard webpage of http://kudu.incubator.apache.org does not work.
    An infra ticket has been created to do the conversion INFRA-11407.

* Miscellaneous

  - The Incubator's Retirement Guide has been substantially refreshed, and
    it should now be easier for a Mentor or other volunteer to perform the
    administrative steps to retire a podling.

  - This month saw a large number of mentors resign from podlings.

  - Brooklyn submitted an IP Clearance on the incubator mailing lists.  
    Last that was seen about the incubators role in IP Clearance was that
    it shouldn't be the gatekeeper of top level projects.

  - The current count of 52 podlings is likely the largest the incubator
    has ever seen.

Shepherd/Mentor notes:

  Great news! The community wrote the report this month! Thank you to
  Lei Pan for pushing forward and I have high hopes over the next few months
  we can light a fire under this project.


--------------------
CommonsRDF

Commons RDF is a set of interfaces and classes for RDF 1.1 concepts and
behaviours.  The commons-rdf-api module defines interfaces and testing
harness.  The commons-rdf-simple module provides a basic reference
implementation to exercise the test harness and clarify API contracts.

CommonsRDF has been incubating since 2015-03-06.

Three most important issues to address in the move towards graduation:

  1. Re-engage and grow the Commons RDF community base
  2. Work with key target communities (initially within Apache) to ensure
     Commons RDF meets potential user requirements and expectations towards
     next versions of the Commons API.
  3. Find lateral target goals that could make the project viable.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  n/a

How has the community developed since the last report?

  Sleeper community in the last months; very few mails and no commits.

How has the project developed since the last report?

  Project's development has completely stop in the last months. We expected
  a different engagement from major RDF toolkits. But since that does not
  happen, we have started to discuss options to find a viability for the
  project https://s.apache.org/oxqb

  By the next reporting period we should have something more concrete
  towards the future, or we could think about a possible exit strategy.

--------------------
Fineract

Fineract is an open source system for core banking as a platform.

Fineract has been incubating since 2015-12-15.

Three most important issues to address in the move towards graduation:

  1. Inform the non-technical part of the existing Mifos.org community of
     the change in project structure
  2. Getting licensing issues figured out for our first release
  3. Replacing dependencies that are not compliant with the license policies

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  None, currently.

How has the community developed since the last report?

  Since the code was initially pushed over, the community is working on the
  first release.

  In addition to the initial committer new contributors started to work on
  the project.

  There is a technical conference in Amsterdam in the second week of March
  during which some contributors and some community members will be
  introduced to developing under the Apache model.

How has the project developed since the last report?

  The initial code is now available and the work to meet the license
  policies has started.

--------------------
Impala

Impala is a high-performance C++ and Java SQL query engine for data stored
in Apache Hadoop-based clusters.

Impala has been incubating since 2015-12-03.

Three most important issues to address in the move towards graduation:

  1. Movement of existing JIRA / Git / wiki resources to Apache
     equivalents
  2. Initial release as incubating project.
  3. Community growth

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  None.

How has the community developed since the last report?

  There have been no additions to the committer or PMC lists since
  incubation began. However, we have seen an uptick in external
  contributions, both through code, and in discussion on the mailing list.
  One contributor has been attempting to port Impala to PPC, and has
  reported some success after asking many questions.

How has the project developed since the last report?

  We have made some slow progress with our initial infrastructure tasks.
  Code review traffic is now copied to dev@impala.incubator.apache.org,
  which means that developer discussions are now happening on the mailing
  lists.

  We have a number of infrastructure tasks ahead of us which are blocked on
  the current Impala team at Cloudera being very busy with an internal
  release (this is one reason we look forward to a more diverse community!).
  For example:

  1. We would like to move our Git repository to .apache.org in short order,
     but as it stands the existing repo is 10GB large and historically
     contains many binary artifacts that, while acceptably licensed, have no
     useful place in Impala's repository. We need to strip these artifacts
     from the Git history, and then adjust Gerrit to commit to the new
     branch in the new repo. This is not hard but takes some time.
  2. We would also like to move our JIRA tickets from issues.cloudera.org to
     issues.apache.org. Experience in a sister podling has shown that this
     isn't straightforward if we wish to preserve existing release labels,
     user assignments and so on, so requires some time.

  We anticipate having much more time to work on these basic issues after
  the end of February. We look forward to getting Impala into a position
  where it is easier for the larger community to collaborate on these kinds
  of project management issues.

Date of last release:

  None since entering incubation.

When were the last committers or PMC members elected?

  None since entering incubation.

--------------------
Kudu

Kudu is a distributed columnar storage engine built for the Apache Hadoop
ecosystem.

Kudu has been incubating since 2015-12-03.

Three most important issues to address in the move towards graduation:

  1. Build a more diverse developer and user community
  2. Migrate our web site under apache.org
  3. Continue to make regular Apache releases

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  None.

How has the community developed since the last report?

  - In February, we only received one patch from a new contributor (3 total
    from non-committers). We're continuing to focus on building a more
    diverse developer community.

    Although recruiting new contributors to Kudu itself have been slow, we
    had community members report beginnings of a Presto integration, an
    Apache Flume sink, and Rust language bindings. We are considering
    whether it makes sense to develop these things within the Kudu project
    or external locations.

  - Overall development velocity continues to be pretty good: 94 patches
    committed since the last report, representing about 3.5kloc of new code
    and 4kloc of changes.  This is slightly down from last month, as we
    spent a bit more time on managing our first release and fixing bugs
    rather than adding new features.

    Dev list traffic is similar to January (1032 messages vs 1144 in Jan).

  - Community members continue to give public talks about Kudu at various
    conferences and meetups. Talks were delivered at conferences or meetups
    in Tokyo (x2), Sunnyvale, Krakow, San Francisco (x2), and Seattle. More
    are planned for March.

    We are also encouraged that at least two Kudu meetup talks were
    delivered by new members of the community outside the core development
    team. We hope to see the "grassroots community" trend continue.

  - The public Kudu Slack channel continues to be popular. It has grown from
    116 members last month to 150 this month. Discussion between users and
    devs is quite active, with daily participation from a global community
    (USA, China, Poland, Japan, et al). Many users seem to prefer this
    method over the traditional user mailing list.

How has the project developed since the last report?

  Since the last report, we've accomplished the following milestones:

  - We successfully migrated our issue tracking to the Apache JIRA. Special
    thanks to Gavin on the infra team and Mike Percy on the Kudu project for
    hard work on this transition.

  - We cleaned up our license documentation and successfully published our
    first official release as an incubating project (0.7.0)!

Date of last release:

  Feb 25, 2016: Apache Kudu 0.7.0-incubating

When were the last committers or PMC members elected?

  None since initial incubation.

log4cxx2

Logging for C++

log4cxx2 has been incubating since 2013-12-09.

Three most important issues to address in the move towards graduation:

  1. Create a release
  2. Activate some community
  3.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

  There's an ongoing discussion to move the project to attic unless it is
  able to release in the next few months.

How has the community developed since the last report?

  Not grown. However, the project aims to become a sub project of Apache
  Logging again. Community growth is not much a matter for this podling, as
  long as there are a few active contributors.

How has the project developed since the last report?

  After the discussion about the activity of the project and the success of
  the incubation process, there's currently a member willing to step through
  the release process. The initial plan on incubation anyway was to primary
  apply available patches and release those bug fixes.

  Additionally, there's once more a discussion about the supported build
  platforms, because currently the project heavily focusses on cpptasks,
  which is not maintained and simply doesn't support current versions of all
  formerly supported IDEs anymore.  The current focus is on dropping
  cpptasks and ANT for the build of the software and use autoconf and/or
  cmake instead.

Date of last release:

  2008-04-03 was the last official, pre-incubation 0.10.0

How has the community developed since the last report?

  We have identified shortcomings in the Initial Committer list, and adopted
  a fast-track process to add new members, valid for the project's first
  three months (until March 20th).  We have welcomed our first genuinely new
  committer and are inviting another.  Initial committers are familiarising
  with Apache.

Singa

Singa is a distributed deep learning platform.

Singa has been incubating since 2015-03-17.

Three most important issues to address in the move towards graduation:

  1. Improve the system, including performance and features like distributed
     GPU training over GPU clusters, R binding, etc.
  2. Add more examples and documentation to attach users
  3. Grow the community. We have been trying to reach out to a more diverse
     community of developers and users by presenting SINGA for various
     audiences. Completing items 1 and 2 above would attract more
     contributors and users.

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?

Shepherd/Mentor notes:

  Andy:: It would be good to have a second active mentor in addition to Dan.
  Chris: I have to retire as a Taverna mentor. That said - what's stopping
  Taverna from being ready to graduate? If it's just mentor activity then consider
  graduating. The community looks active, looks like it's releasing, looks like
  involved in GSoC, etc.
