>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: resourcemanager

>            Reporter: Daryn Sharp
>            Priority: Critical
> The RM stops trying to renew tokens if any exception occurs during the renew. 
>  This should be changed to abort only if the exception is {{InvalidToken}} to 
> allow resilience to transient network failures, issues associated with 
> aborted connections when the NN is overloaded, cluster upgrades, etc.
