Support for testing partitioners

Any update on below request :
https://issues.apache.org/jira/browse/MRUNIT-88?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#issue-tabs

I am also in need of feature of testing partitioners using MRUNit.

Hi,

My guess that JIRA is going to take some time since we need upstream changes.

However, you can test your map/reduce code with MRUnit and test your
Partitioner with JUnit itself.

In pseudo code:

Partitioner part = new Partitioner();
int n = part.getPartition(key, value, numReducers);
assertEquals(5, 1);
