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.
