> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: applicationmaster
> Affects Versions: 0.23.3, 2.0.1-alpha
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Fix For: 3.0.0, 2.0.3-alpha, 0.23.5

>
> 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.
