---------------------------------

             Summary: Add utility function for merging output by identity reduce
                 Key: CRUNCH-162
                 URL: https://issues.apache.org/jira/browse/CRUNCH-162
             Project: Crunch
          Issue Type: Improvement
          Components: MapReduce Patterns
    Affects Versions: 0.4.0
            Reporter: Dave Beech
            Priority: Minor


Something I find myself doing reasonably often in mapreduce is to use
the reduce step as nothing more than a means to merge data into larger
files (using the identity reducer). 

There doesn't appear to be a neat way to do this with Crunch at the moment.
