[jira] [Created] (YARN-674) Slow or failing DelegationToken renewals on submission itself make RM unavailable

Vinod Kumar Vavilapalli created YARN-674:
--------------------------------------------

             Summary: Slow or failing DelegationToken renewals on submission itself make RM unavailable
                 Key: YARN-674
                 URL: https://issues.apache.org/jira/browse/YARN-674
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


This was caused by YARN-280. A slow or a down NameNode for will make it look like RM is unavailable as it may run out of RPC handlers due to blocked client submissions.
