> 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.
