> Key: MAPREDUCE-4157
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4157
> Project: Hadoop Map/Reduce
> Issue Type: Improvement

> Currently when the ApplicationMaster unregisters with the ResourceManager,
> the RM kills (via the NMs) all the active containers for an application.
> This introduces a race where the AM may be trying to clean up and may not
> finish before it is killed. The RM should give the AM a chance to exit
> cleanly on its own rather than always race with a pending kill on shutdown.
