Vinod Kumar Vavilapalli commented on YARN-5079:
-----------------------------------------------
bq. I'm going to go ahead with creating a branch and starting the port
activities.
Created 'yarn-native-services' branch based off trunk.
> [Umbrella] Native YARN framework layer for services and beyond

> Key: YARN-5079
> URL: https://issues.apache.org/jira/browse/YARN-5079
> Project: Hadoop YARN
> Issue Type: New Feature
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Vinod Kumar Vavilapalli

> (See overview doc at YARN-4692, modifying and copy-pasting some of the
> relevant pieces and sub-section 3.3.1 to track the specific sub-item.)
> (This is a companion to YARN-4793 in our effort to simplify the entire story,
> but focusing on APIs)
> So far, YARN by design has restricted itself to having a very low-level API
> that can support any type of application. Frameworks like Apache Hadoop
> MapReduce, Apache Tez, Apache Spark, Apache REEF, Apache Twill, Apache Helix
> and others ended up exposing higher level APIs that end-users can directly
> leverage to build their applications on top of YARN. On the services side,
> Apache Slider has done something similar.
> With our current attention on making services first-class and simplified,
> it's time to take a fresh look at how we can make Apache Hadoop YARN support
> services well out of the box. Beyond the functionality that I outlined in the
> previous sections in the doc on how NodeManagers can be enhanced to help
> services, the biggest missing piece is the framework itself. There is a lot
> of very important functionality that a services' framework can own together
> with YARN in executing services end-to-end.
> In this JIRA I propose we look at having a native Apache Hadoop framework for
> running services natively on YARN.
