MRUnit MapReduceDriver should support combiners

                 Key: MAPREDUCE-797
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-797
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Aaron Kimball
            Assignee: Aaron Kimball
         Attachments: MAPREDUCE-797.patch

The MapReduceDriver allows you to specify a mapper and a reducer class with a simple sort/"shuffle"
between the passes. It would be nice to also support another Reducer implementation being
used as a combiner in the middle.
