Jason Lowe commented on MAPREDUCE-4951: --------------------------------------- Arguably it's yet another instance of the race already covered by MAPREDUCE-4955 as I mentioned above. > Container preemption interpreted as task failure > ------------------------------------------------ > > Key: MAPREDUCE-4951 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4951 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: applicationmaster, mr-am, mrv2 > Affects Versions: 2.0.2-alpha > Reporter: Sandy Ryza > Assignee: Sandy Ryza > Attachments: MAPREDUCE-4951-1.patch, MAPREDUCE-4951.patch > > > When YARN reports a completed container to the MR AM, it always interprets it > as a failure. This can lead to a job failing because too many of its tasks > failed, when in fact they only failed because the scheduler preempted them. > MR needs to recognize the special exit code value of -100 and interpret it as > a container being killed instead of a container failure. -- This message is automatically generated by JIRA.
