Jian He resolved YARN-342.
--------------------------
    Resolution: Not A Problem

I think DFS client will do the retry automatically. Close this as this blocks 2.8
Please reopen if not the case.

>                 URL: https://issues.apache.org/jira/browse/YARN-342
>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: resourcemanager
>    Affects Versions: 2.0.0-alpha, 0.23.6, 3.0.0-alpha1
>            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.
