Reducers don't make "progress" while iterating through values
-------------------------------------------------------------

                 Key: HADOOP-1105
                 URL: https://issues.apache.org/jira/browse/HADOOP-1105
             Project: Hadoop
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.12.0
            Reporter: Owen O'Malley
         Assigned To: Owen O'Malley
             Fix For: 0.13.0


Reduces make progress when they go to a new key, but not when they read the next value, which
could cause reduces to time out when they have a lot of values for the same key.
