             Summary: Improvement to DelegationTokenRenewer in RM
                 Key: YARN-10722
                 URL: https://issues.apache.org/jira/browse/YARN-10722
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: RM, yarn
            Reporter: Fengnan Li
            Assignee: Fengnan Li


We have seen multiple issues related with Yarn DelegationTokenRenewer, especially when namenodes where the token was given had some issues (i.e. standby down). This component has become a SPOF blocking all Yarn applications to be accepted.
