--------------------------------------------------------------
Attached is a patch that adds support for testing jobs that have multiple input
sources (i.e., jobs that would use {{MultipleInputs}} in their job
configuration).
The main contribution is
{{org.apache.hadoop.mrunit.MultipleInputMapReduceDriver}} (old API) and
{{org.apache.hadoop.mrunit.mapreduce.MultipleInputMapReduceDriver}} (new API).
I have included multiple input versions of all of the unit tests in
{{org.apache.hadoop.mrunit.TestMapReduceDriver}} and
{{org.apache.hadoop.mrunit.mapreduce.TestMapReduceDriver}}, respectively.
The patch also includes a slight refactoring of already-existing classes to
enable reuse in the above.
Please let me know your thoughts.

> Add support for MultipleInput
> -----------------------------
>
> Key: MRUNIT-205
> URL: https://issues.apache.org/jira/browse/MRUNIT-205
> Project: MRUnit
> Issue Type: New Feature
> Reporter: Jason E Tedor
> Attachments: MRUNIT-205.patch
>
>
> Some MapReduce jobs have multiple input sources that can even feed different
> Mapper implementations within the same job.
> MRUnit does not have a driver that natively supports testing these types of
> jobs.
> Note that this is not the same as MRUNIT-64. However, there are comments in
> that ticket that adding such support could be a good feature.
