Dave Beech created CRUNCH-162:
---------------------------------
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.
