Yarn client goes into tight loop upon connection failure
--------------------------------------------------------

                 Key: MAPREDUCE-3704
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3704
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
    Affects Versions: 0.23.0, 0.24.0
            Reporter: Daryn Sharp


If the client fails to connect to the AM or HS, it will go into a tight loop 
retrying the connection.  The log rapidly grows with multiple log lines per 
attempt.  Based one of the logs, the client was pounding on the AM ~1000/sec.
