    • Add Combiner support to MapReduceDriver in MRUnit

    Description

      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.
