I have a mapreduce process that has 2 mapper/reducer pairs chained together.

How can I go about unit-testing the whole chain?

I've looked into the MapReduceDriver and can't seem to figure out how to pipe the output of the first job into the second.

Thanks

  • You could chain the jobs really, only in junit you couldn't. right? – Tom Sebastian Oct 31 '14 at 07:12
  • There used to be a PipelineMapReduceDriver for the old Hadoop API for doing that but I can't seem to find the equivalent in the new API. – mfau Oct 31 '14 at 13:21
