[jira] [Created] (MAPREDUCE-5384) Race in DelegationTokenRenewal#RenewalTimerTask

Karthik Kambatla created MAPREDUCE-5384:
-------------------------------------------

             Summary: Race in DelegationTokenRenewal#RenewalTimerTask
                 Key: MAPREDUCE-5384
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5384
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 1.2.1
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


There is a race between cancel() and run() methods of DelegationTokenRenewal.

This is to revisit MAPREDUCE-4860, which introduced a deadlock while fixing this race. Opening a new JIRA per discussion in MAPREDUCE-5364, since MAPREDUCE-4860 is already shipped in a release.
