Testing multiple outputs with MRUnit

Question

Is there a way to test a reduce class with MRUnit that uses MultipleOutputFormat to write to multiple output files?

Answer 1

It looks like support for MultipleOutputs is still work in progress in the MRUnit Jira.

That being said, I found someone who implemented his own drivers subclassing MRUnit's MapReduceDriver to make it work with MultipleOutputs here, hope that helps.

Answer 2

MRUnit 1.1.0 has been released in June 2014 (see http://mrunit.apache.org/)

This latest release includes support for MultipleOutputs (see https://issues.apache.org/jira/browse/MRUNIT-13)
