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

             Summary: Got ClassCastException when using mapreduce.history.server.delegationtoken.required=true
                 Key: MAPREDUCE-4264
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4264
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.3
            Reporter: Thomas Graves
            Assignee: Thomas Graves
            Priority: Blocker


Oozie fails to run on branch-0.23 with the following exception. This only affects branch-0.23
not branch-2 or trunk.

Note that this is caused because oozie passes in the options:  -Dmapreduce.history.server.delegationtoken.required=true
-Dmapreduce.history.server.delegationtoken.renewer="mr token"
