Incubator PMC report for August 2017

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 53 podlings incubating.  July was a quieter month for the incubator, summer holidays and what not.  We executed seven podling releases this month, one podling retired but otherwise no other changes.

* Community

  New IPMC members:

  - None

  People who left the IPMC:

  - None

* New Podlings

  - None

* Podlings that failed to report, expected next month

  - MRQL
  - Ratis

* Graduations

  The board has motions for the following:

  - None

* Retirements

  The following podlings retired this month:

  - HORN

* Releases

  The following releases entered distribution during the month of
  July:

  - 2017-07-06 Apache Gearpump 0.8.4
  - 2017-07-06 Apaceh Traffic Control 2.0.0
  - 2017-07-08 Apache Aria Tosca 0.1.0
  - 2017-07-11 Apahce HAWQ 2.2.0.0
  - 2017-07-18 Apache Griffin 0.1.5
  - 2017-07-18 Apache Aria Tosca 0.1.1
  - 2017-07-31 Apache Guacamole 0.9.13


* IP Clearance

  - We have begun work to clean up IP Clearance policies.  First is to make it clear that the preference is ICLAs and CCLAs over SGAs.  We have also seen better responsiveness after reasserting that the IPMC owns responsibility for all incoming code donations.

* Legal / Trademarks



* Infrastructure



* Miscellaneous

  - A general issue of VPs within other cross functional areas of the ASF reaching out to podlings has started to surface.  Specifically, I would like to request that the board supports a request that those areas should be reaching out to podlings directly with issues, escalating to the IPMC due to lack of follow through, rather than approaching the IPMC first.  The Security team's model is a perfect example of what to do.

BatchEE

BatchEE projects aims to provide a JBatch implementation (aka JSR352) and a
set of useful extensions for this specification.

BatchEE has been incubating since 2013-10-03.

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

  1. Increase the community probably?
  2. -
  3. -

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?

Not much as expected being in between "spec" releases.

How has the project developed since the last report?

BatchEE is quite stable and therefore should probably head to graduation soon.

How would you assess the podling's maturity?

     Comments: I think we should graduate indeed. 
     It seems we had some confusion with the LDAP when we added rsandtner as committer. 
     We need to scan our mailing lists and check what is missing on the official status page.

IPMC/Shepherd notes:
team-list.html - this page shows no members or committers.
I checked private and it looks like the last committer/ppmc add was in Dec 2015.
User ML had questions from only one person at two different times in 2015.
There is activity and it looks like a new release may happen soon.

sessionization, and set and bag operations. DataFu also provides Hadoop jobs
for incremental data processing in MapReduce.

DataFu has been incubating since 2014-01-05.

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

  1. Positive IPMC recommendation vote for graduation
  2. Address any IPMC feedback regarding graduation
  3. Continue 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?

IPMC/Shepherd notes:
Project is ready to graduate. I noticed a problem with their answer to QU30 on the Maturity model.
It was in part a documentation issue. Raised it with the project and they are addressing the way that
they are asking for security issues. Raised the documentation issue with ComDev and we fixed it.

Edgent

Apache Edgent is a programming SDK and micro-kernel style runtime 
that can be embedded in gateways and small footprint edge devices enabling
local, real-time, analytics on the continuous streams of data coming
from equipment, vehicles, systems, appliances, devices and sensors of 
all kinds (for example, Raspberry Pis or smart phones). Working in 
conjunction with centralized analytic systems, Apache Edgent provides 
efficient and timely analytics across the whole IoT ecosystem: from the 
center to the edge.

Edgent has been incubating since 2016-02-29.

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

  1. Create and expand a diverse community of contributors and committers
     around the Edgent project.
  2. Attracting at least another independent committer/ppmc member.
  3. Finding further real world users of Edgent

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?

    * Total, we have 70 subscribers to our mailing list, an improvement
	of 5 since the last report.	
	* We have had a noticeable increase in the number of information-seeking
	emails on the mailing list from new Edgent developers.
	* A San Francisco meetup has been scheduled for the 20th of September
    to demonstrate an Edgent video analytics application which was
	initially presented at ApacheCon 2017 (Video Analytics at the Edge: 
	Fun with Apache Edgent, OpenCV and a Raspberry Pi).
	* In addition to Chris Dutz, we have had one non-committer PR merged.
	

How has the project developed since the last report?

  * With the contributions of Christoper Dutz and Dale LaBossiere, the
	Edgent build system is undergoing an overhaul to Maven from Gradle.
	Maven provides benefits over Gradle, including a more rigid build 
	structure, and the Maven package system.
  * According to JIRA, 13 new issues were added to the project and 6 
    issues have been resolved or closed between May 2017 and August 2017.

How would you assess the podling's maturity?
Edgent is making slow but consistent progress towards graduation. While we
don't yet meet the diversity requirements, we put emphasis on community 
growth through outreach which will ultimately pave the way for additional
committers and contributors.

Additionally, before we graduate it is important that we find users 
outside of IBM. As most Edgent committers are employed by IBM, external 
stakeholders help ensure long term contribution to the project.

   https://lists.apache.org/list.html?dev@impala.apache.org:dfr=2017-2-1|dto=2017-4-30:%22has%20invited%22

Impala has done a third release with a second release manager. Two CVEs were issued, our first ones under the Apache security guidelines.

How has the project developed since the last report?

There have been big changes to the buffer pool, as outlined in https://lists.apache.org/thread.html/f573698455bf2ff9ac2073c778802d0d5c9f3c8be43ede80614259cb@%3Cdev.impala.apache.org%3E . There have also been big changes landing to the RPC layer to improve scalability. Impala now has TABLESAMPLE to allow running queries on only a small percentage of the table for experimenting with queries quickly, and it now works on ADLS.

iota

Open source system that enables the orchestration of IoT devices.

iota has been incubating since 2016-01-20.

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

1. An initial release of iota 
2. Building a more active community
3. Consistency in the discussions on mailing lists/ steady flow of source code
contributions

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?

@crostofolini and @rafaelweingartner are working on integrating the 
Spring framework into iota (pull request 35)

We are waiting on a jar file to be removed from the test suit so that 
an initial release of the software can be produced. (The jar file is related to 
iota tests - need committer to publish the source code - enabling us to remove the
jar artifact enabling the initial release of the software).

The initial release will proceed without the Spring Framework 
Integration. We will add this in a future release.

Ticket's are in place for the initial release.

How has the project developed since the last report?

Interest in using iota (including the Spring Framework) outside the committer group

The email reflectors for dev and users have become more active.

New functionality was added to iota - global performers.

        The release was well organized and delivered thanks to Lewis and Tommaso, it feels to me like the Joshua developers need to be a little more proactive. As the report points out, community building is the biggest issue, I'm going to spend some time in the near future working with the PPMC to see what integrations, tutorials and demos we can do to drive developers and adoption which will hopefully expand the community.

  2. Possibility that NetBeans 1st donation will not be done in time to release together with JDK 9.
  3. Slowness/thoroughness of the process of handing over code from Oracle.

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

The process will take time.

How has the community developed since the last report?

Various discussions about specific plugins, etc, and about the logo and website.

     Comments: Also note that the download page has a note to the effect that the 1.18 release isn't an
               Apache release. The message could be worded better, but at least it is there.

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. Apache Slider community/PPMC has voted to move portions of Slider into
    Apache Hadoop YARN as modules. It is possible that the remaining pieces
    will be moved at a later point in time or become obsolete or evolve to
    work closely with YARN. Slider PPMC will decide what makes the most
    sense as we progress through this exciting time.

 2. Getting more external users

 3. Growth of a diverse set of developers/committers/PMC members is also
    crucial towards the final state of Slider

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?

 Mailing list activity has been lower due to the bulk of the development
 moving to an Apache Hadoop branch. Questions on usage and issues
 encountered by end users keep coming at regular intervals, keeping the DL
 fairly active.

How has the project developed since the last report?

 Work continues in parallel on the Apache Hadoop yarn-native-services
 branch and on the Slider podling. The bulk of the work has been in
 yarn-native-services, while a few Slider patches (related to critical
 issues or agent-only issues) have been committed as well.

    Comments: More work happening in Apache Hadoop YARN project to finish the module move of Slider but it is opaque. Will prod the community to send periodic dev-list updates demonstrating the current progress in this process.

IPMC/Shepherd notes:

  johndament: Based on the description, as well as the little bit of information I've been able to get out of the Slider community, it seems that while there is a Slider community they're not actively working on Slider's codebase.  My recommendation is probably to retire the Slider community if they cannot be absorbed into the Hadoop TLP.

Superset

Superset is an enterprise-ready web application for data exploration, data
visualization and dashboarding.

Superset has been incubating since 2017-05-21.

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

  1. Grow the community and enroll new committers.
  2. Plan and execute our first Apache release 
  3. Address the challenge that React is no longer allowed in Apache projects

Any issues that the Incubator PMC (IPMC) or ASF Board wish/need to be
aware of?
* Superset is heavily reliant upon React, however React has the same patent clause as RocksDB, which ASF had condoned use of until RocksDB backtracked and removed that clause. Our team is concerned about the implications and we are looking for guidance (https://issues.apache.org/jira/browse/LEGAL-320)
* The team is working on finishing up all the items on the Incubation Checklist.


How has the community developed since the last report?
* Organic growth of our Github contributors (148), forks (2,153), watchers
  (770) and stars (15,075)

How has the project developed since the last report?
* The code repository now lives at https://github.com/apache/incubator-superset on Apache’s infrastructure
* We have migrated the project website to the Apache website: http://superset.apache.org/
* A healthy, constant flow of bug fixes, quality improvements and new features, take a look at the project’s Pulse on Github for more details

Unomi

Unomi is a reference implementation of the OASIS Context Server specification
currently being worked on by the OASIS Context Server Technical Committee. It
provides a high-performance user profile and event tracking server.

Unomi has been incubating since 2015-10-05.

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

  1. During the three last months, we did bunch of bug fixes and we are preparing new maintenance release. We also working on a feature branch with major dependencies update (Apache Karaf 4, ...) and refactoring on some Unomi internals (like the tags).
  2. If we did good improvements on the user community front, we would like to increase the developer community and see more contributions.

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 user community grew up (according messages and feedback we go). We think that we are getting close to graduation and we will define an action plan with the topics to address for this.

How has the project developed since the last report?

  We are still preparing 1.2.0-incubating
  release including more bug fixes. 

  We also started a 2.0.0-incubating branch with major dependencies update (Apache Karaf 4.x, Elasticsearch 5.x, ...) and refactoring of some internals.

IPMC/Shepherd notes:

  johndament: Just for clarification, Unomi has PPMC members, not a PMC.  In addition, their website continues to use the old incubator logo.  On the flip side, activity is high on the mailing lists so I'm a bit surprised it took extra effort to get a report submitted.  Keep up the activity levels.
