-----------------------------------

             Summary: hdfs' TestDelegationToken fails intermittently with a race condition
                 Key: HDFS-3374
                 URL: https://issues.apache.org/jira/browse/HDFS-3374
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


The testcase is failing because the MiniDFSCluster is shutdown before the secret manager can change the key, which calls system.exit with no edit streams available.
