Incubator PMC report for Jun 2013
There is nothing very novel or interesting to report this month. The current chair exits
as of this report. The reports below show the usual mixture of informative and not-so-
informative.
Several IP clearances passed via 'lazy consensus.' They couldn't be lazier;
no one on the IPMC (except the Foundation Secretary) indicated that they reviewed
this transactions.

Apache: Project 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. Continue to attract new developers with a variety of skills and viewpoints
2. Develop community skills and knowledge by building some releases
3. Demonstrate community robustness by rotating project tasks among multiple project members
Issues to Call to Attention of PMC or ASF Board:
none
How community has developed since last report:
Mailing list discussions:
There has been active participation in discussions on the developer mailing list, including new participants and developers. A few have participated in the users list; mainly activity takes place on developer mailing list.
Activity summary:
http://mail-archives.apache.org/mod_mbox/incubator-drill-dev/
June to date 5 June, 29 (mainly jira; some discussion)
May 2013, 135 (jira, focused discussions)
April 2013, 188 (jira; focused discussions)
March 2013 260 (jira, focused discussions)
Topics in discussion on the dev mailing list included but not limited to:
* Evolution of logical plan syntax with addition of operators including the Value and Union Distinct operators
* Advantages and disadvantages of Parquet versus ORC
* ValueVector construct and requirements
* The relative performance of Janino based compilation versus javax.tools.Javacompiler
* Initial development of execution engine environment
* Discussion of various types of large array and off heap data structure libraries
* RPC protocol and framework
Code
For details of code commits, see http://bit.ly/14YPXN9 and http://bit.ly/19IyID1
There has been great progress around both evolution of the reference interpreter and

* Initial implementation of RPC framework
* Base client and Zookeeper based client abstraction
* SQL parser with JDBC driver
* Distributed query scheduling framework
* ValueVector implementations
* Large number of reference interpreter tests and fixes
Community Interactions
There is now a weekly Drill hangout conducted remotely through Google hangouts Tuesday mornings 9am Pacific Time to keep core developers in contact in realtime despite geographical separation. Results from these discussions are shared with the discussion list through meeting minutes and all are welcome to attend. This has been helpful in speeding development and averages attendance of 8-10 developers each week.
Presentations
There have been presentations from community members at conferences, meet-ups and through the weekly Google hangout.
* As you can see from http://drill-user.org/ there were few more HUGs/BUGs where Drill was presented/discussed (in Europe) - the blog itself might also be considered to manifest a contribution (?)
* We have published an article on Drill in the Big Data journal http://www.liebertpub.com/big
Sample presentations:
* Introduction to Apache Drill, Bay Area Analytics Group 2 April 2013 by Tomer Shiran
* Interactive Ad hoc query at scale: talk at Hadoop User Group UK by @mhausenblas

jclouds
A cloud agnostic library that enables developers to access a variety of supported cloud providers using one API
jclouds has been incubating since 2013-04-29.
Three most important issues to address in the move towards graduation:
1. We are working on our first release - iterating over issues currently, making sure we have a proper ASF release ready to go.
2. Since this is the first ASF project for some of the committers, it's taking some time for everyone to adjust to the Apache way, but we're getting there.
3. We need to figure out details on our wiki and site implementaiton.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?
Not particularly - we're definitely edging against some of the boundaries of what's allowed in an Apache project re: license headers, specifically in test expectation files, but we're getting there.
How has the community developed since the last report?
The community is roughly the same - no changes in committer list. We have continued to receive patch submissions and JIRAs from new people, which is, of course, great.
How has the project developed since the last report?
A lot. =) More specifically:
* We've moved our source to the Apache git repos.
* We've moved to ASF JIRA and mailing lists.
* We've renamed our Maven groupIds to org.apache.jclouds, and are publishing SNAPSHOTs to repository.apache.org.
* The jclouds.{org,com,net} domain names have been transferred to Apache, and the jclouds trademark is en route.
* We've been working on RCs for Apache jclouds 1.6.1-incubating, ironing out the many little gotchas, license issues, etc that are to be expected when folding such a large, complex existing project into the ASF. We hope to have a viable final RC presented to the IPMC for voting within a week or so, assuming our mentors sign off on the next RC.
Date of last release:
No ASF release yet.

--------------------
Kalumet
Kalumet a complete environment manager and deployer including J2EE environments (application servers, applications, etc), softwares, and resources.
Kalumet has been incubating since 2011-09-20.
Three most important issues to address in the move towards graduation:
1. Release 0.6.0-incubator (fixes on the legal files)
2. Complete the documentation
3. Refactore the console
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?
None so far
How has the community developed since the last report?
We submitted Kalumet 0.6.0-incubating release to vote, not approved by an IPMC as it requires some fixes on legal files (NOTICE especially).
We submitted a talk to ApacheCon NA, but the talk has not been choosed.
This talk presents Kalumet, with the current features and the roadmap. It has been given to different "local" events in Europe.
How has the project developed since the last report?
We created the Jira corresponding to the changes that we want to include in Kalumet releases.
We decided to increase the release cycle in order to give more visibility to the users, as soon as 0.6.0-incubating will be out.
We completed a first documentation. The documentation will be part of the 0.6.0-incubating release and is also available directly on the website.
Date of last release:
- 0.6.0-incubating submitted 2 times (September, 2012 and November, 2012), but not cancelled.
- This release is in preparation with the legal fixes

Knox
Knox Gateway is a system that provides a single point of secure access for Apache Hadoop clusters.
Knox has been incubating since 2013-02-22.
Three most important issues to address in the move towards graduation:
1. Expand community to include more diverse committers.
2. Align technically with security work going in in Hadoop.
3. Clear the project name with legal and pick a new name if required.
Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be aware of?
1. None
How has the community developed since the last report?
1. No new PPMC members or committers added since last report,
though commits now coming from Larry and Kevin instead of mostly
Kevin which is great.
How has the project developed since the last report?
1. 53 open issues out of 71 issues currently in JIRA.
2. ReviewBoard is set up per INFRA-6068.
3. Discussion underway to set up Git/JIRA integration.

MRQL
MRQL is a query processing and optimization system for large-scale, distributed data analysis, built on top of Apache Hadoop and Hama.
MRQL has been incubating since 2013-03-13.
Three most important issues to address in the move towards graduation:
1. Complete the first release
a) Ensure proper transfer of code
b) Verify distribution rights
2. Establish whether "Apache MRQL" is a suitable name
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 posted a project description on the HadoopSphere blog, which
initiated some discussion and interest. Since the last report, there
was little activity in recruiting new users and developers, but we are
very close to completing the first release. We believe that, as soon
as we make the first release available, many users will start using
the system, will request bug fixes, improvements, and additional
functionality, and will become new contributors.
How has the project developed since the last report?
We are in the process of completing the MRQL codebase to make it ready
for the first release, which we expect to take place in the next few
weeks. The only major component missing that delays this release is
switching to maven as our project management tool. We believe that
using maven is important because it will facilitate contributions by
(and recruitment of) committers and will ease version management. The
reasons for the delay are: 1) no one of the current developers has
prior experience with maven 2) the codebase is non-standard because it
uses non-standard tools to generate Java code.
Date of last release:
none yet

Open Climate Workbench
Apache Open Climate Workbench (Incubating) is an effort to develop software that performs climate model evaluation using model outputs from a variety of different sources (the Earth System Grid Federation, the Coordinated Regional Downscaling Experiment, the U.S. National Climate Assessment and the North American Regional Climate Change Assessment Program) and temporal/spatial scales with remote sensing data from NASA, NOAA and other agencies. The toolkit includes capabilities for regridding, metrics computation and visualization.
Open Climate Workbench has been incubating since 2013-02-15.
Three most important issues to address in the move towards graduation:
1. Develop an Apache community for Open Climate Workbench and connect to other relevant Apache efforts (Tika, Hadoop, SIS, OODT)
2. Make an initial release.
3. Add new contributors to the project.
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?
We're up to 86% (24) of the initial project members having ICLAs on file and accounts. We've got 14% more (4) people still who have yet to submit their ICLA. Chris Douglas and Chris Mattmann have reached out to Bruce Hewitson to submit ICLA. 3 NASA participants from the original proposal are working on their getting their ICLAs approved. Chris Jack from University of Cape Town just had his account created.
Community is now discussing many issues on list: 5 threads (deprecation policy; ideas to improve the metrics module; proposed tool refactoring; tools for Apache Open Climate Workbench; and coding style are all being actively discussed.
How has the project developed since the last report?
* Wiki now being used: https://cwiki.apache.org/confluence/display/CLIMATE/Index
* Review Board reviews are being leveraged; as is JIRA.
* Commit activity is high; and not singled out to Mike Joyce and Cameron Goodale any longer (Whitehall; Huikyo Lee; now contributing)
* The project discussed and decided to add new JIRA issue labels for users pointing out which issues are e.g., easy, more difficult, etc., to tackle. Worked with Gav in infra to set this up.
* The team is discussing cutting a 0.1-incubating RC.

No new PPMC members or committers added since the last report. We need
to work to do a better job of identifying new contributors, but there
is great activity so I don't think this will be a big issue.
Another here that we need to do a better job of here is discussing issues
on list. I see lots of JIRAs and commits, but few [DISCUSS] and other threads.
There was a discussion of merging TEZ-1 which is great though.
How has the project developed since the last report?

Wave
Wave is rich, web-based, distributed, collaboration platform that allows
users to interact in near real time. The wave platform includes a
web-based user interface containing an rich-text. The system is
extendable though widgets, robots, and editor doodads. The Wave In a Box
implementation is developed in java using a variety of web technologies
such as Web Sockets, Java Script, GWT, and supported by an operational
transform based conflict resolution algorithm.
Wave has been incubating since 2010-12-04.
Three most important issues to address in the move towards graduation:
1. Finish the initial release
2. Continue increasing the community size
3. Improve documentation for new users
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?
The last month has seen significantly increased activity on the mailing list regarding long-term visions on where the Wave project should be heading, with an influx of new people (mostly as potential users) discussing how they can help the project. At one of their suggestions, a public discussion was held to help with Wave's publicity, with the aim to bring more people to the project.
How has the project developed since the last report?
Much progress has been made towards an initial release (named 0.4), with RC2 and RC3 having votes on the wave-dev list. RC3's vote ends on the 8th June and is looking likely to be submitted for a vote on the general incubator list within the next few days.
Meanwhile development has continued on the trunk, receiving 5 review requests with the last week from 3 different people (2 new to the project).
The documentation has also seen work, with 3 people have been granted wiki access to help.

Shepherd notes:
The report is very accurate and Wave is actually ways more active than before. All ideas of moving it to the attic/github should be delayed, as the project might have a chance to succeed, if the activity persists. From the mentors, only Upayavira is active. Not heard of any of the others the past period. (grobmeier)
