             Summary: Potential race between renew and cancel in DelegationTokenRenwer 
                 Key: YARN-2919
                 URL: https://issues.apache.org/jira/browse/YARN-2919

    Affects Versions: 2.6.0
            Reporter: Karthik Kambatla

YARN-2874 fixes a deadlock in DelegationTokenRenewer, but there is still a race because of
which a renewal in flight isn't interrupted by a cancel.
