             Summary: MultipleInputsMapDriver
                 Key: MRUNIT-222
                 URL: https://issues.apache.org/jira/browse/MRUNIT-222
             Project: MRUnit
          Issue Type: New Feature
    Affects Versions: 1.1.0
            Reporter: Jens Kristian Geyti
            Priority: Minor


{{MultipleInputsMapReduceDriver}} allows you to test jobs relying on 
{{MultipleInputs}}. 

Such jobs can have no reducer in hadoop, but no {{MultipleInputsMapDriver}} 
exists, and {{MultipleInputsMapReduceDriver}} throws 
{{java.lang.IllegalStateException: No reducer class was provided}} if no 
reducer is set using {{MultipleInputsMapReduceDriver.setReducer(Reducer)}}.

I'd love to look into supplying a patch/pull request, but wanted to be sure 
this is an actual omission, to which a new driver would be welcomed.
