>                 URL: https://issues.apache.org/jira/browse/MRUNIT-213
>             Project: MRUnit
>          Issue Type: Bug
>    Affects Versions: 1.1.0
>         Environment: OSX, IntelliJ, CDH4.6.0
>            Reporter: John Conwell

> I pulled the unit test for testing multiple outputs for a reducer from the patch of MRUNIT-13
and the test fails with the exception:
> java.lang.IllegalArgumentException: Named output 'test' not defined
> 	at org.apache.hadoop.mapreduce.lib.output.MultipleOutputs.checkNamedOutputName(MultipleOutputs.java:188)
> 	at org.apache.hadoop.mapreduce.lib.output.MultipleOutputs.write(MultipleOutputs.java:358)
> 	at org.apache.hadoop.mapreduce.lib.output.MultipleOutputs.write(MultipleOutputs.java:343)
> It looks like multiple reducer outputs needs to be setup in the Configuration object
the same way MultipleOutputs.addNamedOutput() does.
> I'm running cdh4.6.0
