[jira] [Created] (YARN-3472) Possible leak in DelegationTokenRenewer#allTokens

Jian He created YARN-3472:
-----------------------------

             Summary: Possible leak in DelegationTokenRenewer#allTokens 
                 Key: YARN-3472
                 URL: https://issues.apache.org/jira/browse/YARN-3472
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jian He


When old token is expiring and being removed, it's not removed from the allTokens map, resulting in possible leak. 
{code}
if (t.token.getKind().equals(new Text("HDFS_DELEGATION_TOKEN"))) {
              iter.remove();
              t.cancelTimer();
              LOG.info("Removed expiring token " + t);
            }
{code}
