Subject [jira] [Comment Edited] (YARN-7565) Yarn service pre-maturely releases the container after AM restart
Date Wed, 06 Dec 2017 00:27:00 GMT

---------------------------------------------------------------

Patch 2
- Addressed [~jianhe]'s comments
- Instead of checking repeatedly if containers are recovered, made the change in ServiceScheduler
to check just once if the unRecovered containers are still there. If they haven't been recovered
by then, then the container is released and component instance is added to pending queue.
- Added another test

> With YARN-6168, recovered containers can be reported to AM in response to the AM heartbeat.

> Currently, the Service Master will release the containers, that are not reported in the
AM registration response, immediately.
> Instead, the master can wait for a configured amount of time for the containers to be
recovered by RM. These containers are sent to AM in the heartbeat response. Once a container
is not reported in the configured interval, it can be released by the master.
