JobTracker should be able to renew delegation token over HTTP
-------------------------------------------------------------

                 Key: MAPREDUCE-2420
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2420
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.20.4
            Reporter: Boris Shkolnik
            Assignee: Boris Shkolnik


in case JobTracker has to talk to a NameNode running a different version (RPC version mismatch),
Jobtracker should be able to fall back to HTTP renewal.

Example of the case - running distcp between different versions using hfpt.
