Vinod Kumar Vavilapalli commented on YARN-1040:
-----------------------------------------------
bq. If you guys are fine with it, I plan to open separate JIRAs, under
YARN-4726 breaking up this work. I feel we can have more focused discussion
there on specific aspects of the design.

> Key: YARN-1040
> URL: https://issues.apache.org/jira/browse/YARN-1040
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: nodemanager
> Affects Versions: 3.0.0
> Reporter: Steve Loughran
> Attachments: YARN-1040-rough-design.pdf

> The AM should be able to exec >1 process in a container, rather than have the
> NM automatically release the container when the single process exits.
> This would let an AM restart a process on the same container repeatedly,
> which for HBase would offer locality on a restarted region server.
> We may also want the ability to exec multiple processes in parallel, so that
> something could be run in the container while a long-lived process was
> already running. This can be useful in monitoring and reconfiguring the
> long-lived process, as well as shutting it down.
