Summary: Remove duplicated set/add/withInput methods
Key: MRUNIT-139
URL: https://issues.apache.org/jira/browse/MRUNIT-139
Project: MRUnit
Issue Type: Improvement
Reporter: Bertrand Dechoux
Related to MRUNIT-137 : Remove duplicated set/add/withOutput methods
The input is quite similar : a key and a value, except that in the case of the
reducer the value is typed as a list of values.
Mapper : f(a,b) => list<pair<c,d>>
Reducer : f(a',list<b'>) => list<pair<c',d'>>
It would be nice to completely remove the duplication. And also, treating the
reduce input as an iterator over <k,v> rather than <k,list<v>> would be closer
to the implementation that mapreduce uses behind the scenes.
