Vinod Kumar Vavilapalli commented on MAPREDUCE-3347:
----------------------------------------------------
Ramgopal, do you have retries enabled? Bump yarn.resourcemanager.am.max-retries
to say 3 or 4 and retry with a fresh cluster. The default value is 1, so the
retry is off by default.
> Resource manager is not respawning MRAppMaster process if it goes down in the
> middle of job execution and the job is getting failed.
