Subject [Incubator Wiki] Update of "November2016" by GourSaha
Date Thu, 03 Nov 2016 16:29:50 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Incubator Wiki" for change notification.

The "November2016" page has been changed by GourSaha:

  Three most important issues to address in the move towards graduation:
-   1.
-   2.
-   3.
+   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?
- How has the project developed since the last report?
+ How has the community developed since the last report?
+ The Apache Hadoop YARN community/PMC and Apache Slider community/PPMC
+ had decided to move portions of Slider into YARN, to make fast and significant
+ progress on: YARN-4692 - [Umbrella] Simplified and first-class support for
+ services in YARN. As a result, the Slider Core module (including Application
+ Master, Client and Java unit tests) has been rolled into an Apache Hadoop
+ YARN feature branch as a hadoop-yarn-slider-core module.
+ This effort is being captured in: YARN-5079 : Native YARN framework layer
+ for services. All the migrations are happening in a branch (namely
+ yarn-native-services) created of off Hadoop trunk. As a result of this,
+ we are already seeing interest in the Hadoop committers/PMC, who have
+ started to contribute and submit patches to Slider.
+ In order to support existing users of Slider, and to provide seamless
+ migration, there will be sufficient overlap between the time when a stable
+ state of long running services support is available in some future version
+ of YARN and the time till an independent Slider release is available. The
+ community/PPMC will also determine the future state of Slider as we
+ navigate through these changes.
- Date of last release:
+ The discussions on the Slider and YARN community DLs can be viewed here -
- When were the last committers or PMC members elected?
+ For the benefit of those who would like to use Slider Core from the
+ Hadoop codebase, but continue to use classic Slider Agent and legacy
+ app-packages, a new branch (yarn-native-services) has been created
+ in classic Slider repo. This branch retains only the Agent (python) code
+ and the App Packages. It adds Slider Core module as a Hadoop
+ dependency. This allows users to consume the latest of Slider Core.
+ Future classic Slider releases can be made purely off of this branch.
+ Additionally an effort is being made to create an agent-less provider for
+ legacy app-packages, which could help users to completely migrate to
+ Hadoop codebase for creating long-running services with Slider. Expectation
+ from app-package owners would be to make minor modification of their
+ packages. Primary changes would be to shed the dependency on python
+ Agent code, effectively making packages much simpler than what they
+ look like today in classic Slider.
+ How has the project developed since the last report?
+ There has been fewer bug fixes on the classic Slider side as most of
+ the focus has been on developing features on native YARN services in
+ the Hadoop codebase. Work continues on support for complex services
+ (assemblies) and agent-less applications in Slider. The efforts on Slider
+ Core will continue in the new services branch created in YARN. Few
+ key features which were merged to classic Slider as well were -
+ SLIDER-875 - Ability to create an Uber application package with
+ capability to deploy and manage as a single business app, and
+ SLIDER-1107 - Generate app configuration files in AM. Several issues
+ identified by Coverity scans were resolved as well. Additionally few
+ patches were contributed by the community fixing functional and
+ performance issues. Slider community plans to ship a release in the
+ next quarter with all these features and bug fixes.
+ Date of last release:
+   2016-06-28 slider-0.91.0-incubating
+ When were the last committers or PMC members elected?
