Junping Du commented on YARN-5197:
----------------------------------

I think the patch goes to branch-2.8 as well. Add 2.8 in fix version.

> Once a node reports a container running in a status update, the corresponding RMNodeImpl
will track the container in its launchedContainers map.  If the node somehow misses sending
the completed container status to the RM and the container simply disappears from subsequent
heartbeats, the container will leak in launchedContainers forever and the container completion
event will not be sent to the scheduler.
