Devaraj K commented on YARN-3194:
---------------------------------
Thanks [~rohithsharma] for reporting and [~jianhe] for your inputs.
I am also able to reproduce this issue, I see that RM is not getting
information about the completed containers after NM restart as part of the
nodeheartbeat request and also AM is not informing the RM to release these
completed containers. As a result RM is assuming these containers are running
and not releasing these completed container resources.
> After NM restart,completed containers are not released which are sent during
> NM registration
