Jason Lowe commented on MAPREDUCE-4833: --------------------------------------- +1, thanks for writing a test. > Task can get stuck in FAIL_CONTAINER_CLEANUP > -------------------------------------------- > > Key: MAPREDUCE-4833 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4833 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: applicationmaster, mrv2 > Affects Versions: 0.23.5 > Reporter: Robert Joseph Evans > Assignee: Robert Parker > Priority: Critical > Attachments: MAPREDUCE4833-1.patch, MAPREDUCE4833-2.patch, > MAPREDUCE4833.patch > > > 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. -- This message is automatically generated by JIRA.
