> Key: MAPREDUCE-4797
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-4797
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: applicationmaster
> Affects Versions: 2.0.1-alpha, 0.23.3
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Attachments: MAPREDUCE-4797.patch

>
> If LocalContainerAllocator has trouble communicating with the RM it can end
> up retrying forever if the nature of the error is not a YarnException.
> This can be particulary bad if the connection went down because the cluster
> was reset such that the RM and NM have lost track of the process and
> therefore nothing else will eventually kill the process. In this scenario,
> the looping AM continues to pelt the RM with connection requests every second
> using a stale token, and the RM logs the SASL exceptions over and over.
