Robert Parker updated MAPREDUCE-4833:
-------------------------------------
Release Note: (was: Previously the Container did not send an event on
kill if it was DONE, and returned (essentially a no-op). This patch will send a
TA_CONTAINER_CLEANED event in all cases.)
> Task can get stuck in FAIL_CONTAINER_CLEANUP

> Issue Type: Bug

> If an NM goes down and the AM still tries to launch a container on it the
> ContainerLauncherImpl can get stuck in an RPC timeout. At the same time the
> RM may notice that the NM has gone away and inform the AM of this, this
> triggers a TA_FAILMSG. If the TA_FAILMSG arrives at the TaskAttemptImpl
> before the TA_CONTAINER_LAUNCH_FAILED message then the task attempt will try
> to kill the container, but the ContainerLauncherImpl will not send back a
> TA_CONTAINER_CLEANED event causing the attempt to be stuck.
