Subject [jira] [Created] (YARN-1363) Get / Cancel / Renew delegation token api should be non blocking
Date Tue, 29 Oct 2013 20:19:25 GMT
Omkar Vinit Joshi created YARN-1363:
---------------------------------------

             Summary: Get / Cancel / Renew delegation token api should be non blocking
                 Key: YARN-1363
                 URL: https://issues.apache.org/jira/browse/YARN-1363
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Omkar Vinit Joshi
            Assignee: Omkar Vinit Joshi


Today GetDelgationToken, CancelDelegationToken and RenewDelegationToken are all blocking apis.
* As a part of these calls we try to update RMStateStore and that may slow it down.
* Now as we have limited number of client request handlers we may fill up client handlers
quickly.
