Incubator PMC report for June 2014

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 currently 34 podlings under incubation. Two new podlings joined 
the Apache Incubator in May, two podlings graduated. 

* Community

  New IPMC members:

    John D. Ament

  People who left the IPMC:

    (none)

* New Podlings

    Optiq
    Parquet

* Graduations

    Phoenix 
    Stratos

  The board has motions for the following:

    (none)

* Releases

  The following releases were made since the last Incubator report:

    metamodel-4.1.0-RC1-incubating
    odftoolkit-0.6.1-incubating
    sentry-1.3.0-incubating
    slider-0.30-incubating
    spark-0.8.1-incubating

   ODF Toolkit's release was approved using the alternative voting
   process worked out last November/December.  We believe that's the first
   official release in the history of the Foundation that passed with 
   binding votes by non-PMC members.

* IP Clearance
    
    Cray donated a set of libraries called Hadoop RDF Tools, and a VOTE 
    to accept the tools was called by Rob Vesse. The vote passed by lazy
    consensus after 72 hours. No objections or points of discussion were
    raised during the VOTE.

* Legal / Trademarks

    New name for Stratosphere, now Flink. 

* Infrastructure

  Apache Podlings affected by ASF mail outage from May 7th through 
  May 10th, and extended recovery period to deliver backlog.

* Miscellaneous

  S4 failed to report this month, and has been generally inactive. It
  is likely that S4 will be retired, though the PPMC has not voted yet
  to do so.

  NPanday failed to report in a previous cycle, but was accidentally
  dropped from the reporting schedule for this month. NPanday developers
  and mentors were contacted. In 72 hours nobody was available to
  report on the project. Given consistent troubles with getting project
  to report and project mentors MiA, IPMC will look into a resolution.

Brooklyn

Brooklyn is a framework for modeling, monitoring, and managing applications
through autonomic blueprints.

Brooklyn has been incubating since 2014-05-01.

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

  1. Migrating fully to Apache infrastructure (mainly concerning open
     pull requests and issue tracker)
  2. Forming a diverse community and PPMC
  3. Learning and following "the Apache way"

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

  No.

How has the community developed since the last report?

  This is our first report; our community remains very similar to the
  point where we joined the Incubator.

How has the project developed since the last report?

  This is our first report; our project remains very similar to the
  point where we joined the Incubator.

Date of last release:

  No new committers since we joined the Incubator.

--------------------
DeviceMap

Apache DeviceMap is a data repository containing device information, images
and other relevant information for all sorts of mobile devices, e.g.
smartphones and tablets. While the focus is initially on that data, APIs
will also be created to use and manage it.

DeviceMap has been incubating since 2012-01-03.

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

  1. Grow community.
  2. Generate a release.
  3. Explore options to allow contributions through a Web based
     interface/API to add new device specs.
  4. Improved support for additional languages/platform (.NET, PHP,...)

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

  (None)

Drill

Description:

Apache Drill is a distributed system for interactive analysis of large-scale
datasets that is based on Google's Dremel. Its goal is to efficiently
process nested data, scale to 10,000 servers or more and to be able to
process petabyes of data and trillions of records in seconds.

Drill has been incubating since 2012-08-11.

Three Issues to Address in Move to Graduation:

  1. Complete the 1.0 feature set (team targets next release and graduation
     in the month of July)
  2. Continue to attract new developers/contributors with a variety of
     skills and viewpoints
  3. Continue the outreach activities to build the early user community for
     the technology

Issues to Call to Attention of PMC or ASF Board:

  None
 
How community has developed since last report:

  Community awareness and outreach were strengthened in multiple forums as
  below

  * First Apache Drill Hackathon was organized on 4/24. Over 40 participants
    including members from Visa, Linkedin, Cisco, Hortonworks worked to
    harden/enhance Drill project. Several new features have been added to
    Drill product Array reference functions, enhanced Optiq support, Kafka
    storage plugin, robust testing framework etc

How project has developed since last report

  Significant progress is being made on the performance and distributed
  optimization

  C++ client API and ODBC driver leveraging the C++ API was built for Drill
  by a group led by George Chow in Vancouver. The initial drops for the
  driver are available

  New functionality has been added to the product namely distributed
  optimization, join order optimization, Table/view creation, repeated map
  support, HBase support, expanded SQL support, Text readers, new data types
  and functions, Session options for query tuning and lot more

  Nearly ~500 bugs files and ~400 bugs resolved

  Significant progress on running ANSI standard queries such as TPC-H

  Significant code drops have been checked in from a number of contributors
  and committers

  New docs have been published on Drill wiki (Apache Drill in 10 mins,
  Working with various data sources and Installing and Running Apache Drill
  on a cluster)

  Work toward a Beta milestone is progressing substantially.

data motion, coordination of data pipelines, lifecycle management, and data
discovery. Falcon enables end consumers to quickly onboard their data and
its associated processing and management tasks on Hadoop clusters.

Falcon has been incubating since 2013-03-27.

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

  1. Continue to build a broader community
  2. Add more committers to the project

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

  * No

How has the community developed since the last report?

  * More users & contributors have joined the falcon project and the
    community continues to grow rapidly
  * We have had 2 Birds of Feather for Falcon at Hadoop Summit, Europe and
    USA. There were quite a few registered users

--------------------
Flink

Flink is an open source system for expressive, declarative, fast, and
efficient data analysis. Flink combines the scalability and programming
flexibility of distributed MapReduce-like platforms with the efficiency,
out- of-core execution, and query optimization capabilities found in
parallel databases.

Flink has been incubating since 2014-04-14.

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

  1. Infrastructure setup (git, JIRA, mailing list renaming)
  2. Release
  3. Build an ASF community

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?

  The community still "lives" outside the ASF since the infrastructure is
  not ready.

  Two new contributors opened pull requests since the last report.

How has the project developed since the last report?

  The community has voted for a new name, so the project is moving away from
  its old name "Stratosphere" to the new one: "Flink".

  We are still waiting for Infra to rename the mailing list, to create a
  JIRA (blocked by the mailing list) and create a Git repository (blocked by
  the SGA (which we already provided)).

  We released a new major release (0.5) outside the ASF.

Date of last release:

  2014-05-31 (no incubator release yet)

When were the last committers or PMC members elected?

  Only initial committers.

Shepherd/Mentor notes:

  Konstantin Boudnik (cos):

    Project dev@ list has healthy traffic.  Some of the mentors are active
    on the list and helping community. No visible issues.

--------------------
log4cxx2

Logging for C++

log4cxx2 has been incubating since 2013-12-09.

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

  1. We probably need to decide what's an acceptable platform/compiler list,
     sort out any remaining hiccups, and then move towards a release.
  2. We need to release 0.11.0 as maintenance release done via ASF
  3. We need to make a broader use of the ASF infrastructure
     (notably the CI, as well as improved management of the Jira
     site - notably with triaging), and establish a roadmap for
     the next releases.

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?

  No changes in team.

How has the project developed since the last report?

  We are actively supporting the project. Mails suggest that there's work
  going on in the background by some committers especially regarding the
  build process, but there hasn't been any notable commit in the last weeks.
  The current trunk now fixes most of the important outstanding bugs.

Date of last release:

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

  Many post-0.10.0 commits exist on trunk which we intend to get out as
  0.11.x.

environments (application servers, applications, etc), softwares, and
resources.

Kalumet has been incubating since 2011-09-20.

No report submitted this month.

Shepherd/Mentor notes:

  Justin Mclean (jmclean):

    Podling may be in a little trouble. Failed to report this month, mailing
    list traffic and commits at a very low level. A mentor is still active
    but looks likes like the last release candidate (October 2013) wasn't
    voted on by the IPMC and a new release candidate hasn't been created.
    Last report talked about graduation so perhaps they just need some help
    in getting past the final hurdle?

--------------------
MRQL

MRQL is a query processing and optimization system for large-scale,
distributed data analysis, built on top of Apache Hadoop, Hama, and Spark.

MRQL has been incubating since 2013-03-13.

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

  1. increase adoption, expand user community, and increase user list
     activity
  2. have at least one more incubator release

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?

  A new PMC member was elected, Moon Soo Lee. The company DataSayer and the
  project Zeppelin (zeppelin-project.org) are now using MRQL.

How has the project developed since the last report?

  We have switched to Junit for query testing, instead of evaluating queries
  from files using plain Java code. New tests were introduced and some bugs
  were corrected based on these tests.

  - Finish bootstrapping project, IP clearance, initial website
  - Expanding the community and adding new committers
  - 1st release

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

  - None at this time

How has the community developed since the last report?

    created. The mailing lists have been setup and we are starting to use
    them for communication.

How has the project developed since the last report?

  - We have setup the incubator status page and are waiting on the final
    SGA to be sent in to start the code import (INFRA-7782)

Date of last release

  - No releases as of yet. Working through initial IP clearance.

When were the last committers or PMC members elected?

  - N/A, still bootstrapping the project.

--------------------
Sentry

Sentry is a highly modular system for providing fine grained role based
authorization to both data and metadata stored on an Apache Hadoop cluster.

Sentry has been incubating since 2013-08-08.

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

  1. Grow the Sentry community
  2. Add new committers that diversify the project
  3. Continue to release at regular intervals

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

  The community is growing. A number of new members have started actively
  contributing to the project.

How has the project developed since the last report?

  The project did its 2nd release from incubation. Thanks to lot of hard
  work from the release manage Karthik Ramchandran and other community
  members, version 1.3 was released earlier this month. The db backed policy
  store feature branch is merged into master. The community is working
  towards improving that functionality and stabilization.

Date of last release:

  2014-05-15

When were the last committers or PMC members elected?

  Vamsee Yarlagadda has been added as a committer as announced on Feb 28,

--------------------
Slider

Slider is a collection of tools and technologies to package, deploy, and
manage long running applications on Apache Hadoop YARN clusters.

Slider has been incubating since 2014-04-29.

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

  1. Podling name search
  2. Growing user community
  3. Growing and increasing diversity of developer community

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?

  We're only getting started, and do not have any diversity yet. Our first
  goal will be to get users, bug reporters and developers. The dev list is
  up and running -and we do not have any separate user list, so we hope to
  pull users into coding.

  The initial release will help to gain awareness, and should bring in
  users.

How has the project developed since the last report?

  Our main activity has been setting up the incubator-hosted project, JIRA,
  site, mailing list. etc. The Infra team have been very helpful here.

  - Making and publishing our site has educated us on site publishing
  - The initial release has taught us of the release process for incubating
    projects, and where we need to improve it.

  We're still trying to get Jenkins building, but that's a matter of
  handling protobuf-versions on the build machines, rather than infra
  involvement.

  We have made our first ASF-hosted release on June 2. This was a source
  only release; some of the reviewers have made suggestions which will need
  to be incorporated into the next. We plan to do another release in a few
  weeks time, and so evolve the project rapidly.

Date of last release:

  2014-06-02

When were the last committers or PMC members elected?

We have only just set up and so the committer and PMC membership is
as covered in the incubator proposal.

  1. Community growth
  2. Next release
  3. Documentation improvements

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?

 We have added on additional committer and community activity in the mailing
 lists continues to grow.

How has the project developed since the last report?

 We have held a logo contest and completed the first of two rounds of
 voting.  Final logo selection will take place shortly. We have also
 established a feature branch for incorporating all the security work done
 by the engineering team at Yahoo!. Having the option for secure Storm
 deployments will play a big role in increasing enterprise adoption.

 We plan on initiating our next release next week in addition to completing
 the logo contest. Once these two tasks are complete we would like to
 consider beginning the graduation process.
