Here ya go!

MRUnit is a unit testing framework specifically designed to make it easy
to test and evaluate Map Reduce algorithms and applications that run on 
top of Hadoop.

MRUnit entered the Incubator on Mar 8, 2011.

We just elected a new committer (Jim Donofrio), and before that we elected
Brock Noland, who has been really leading the way.

We could probably use another elected committer but the good news is that
we are really getting some good participation from contributors now.

Sure that would be great. The more the merrier, I think. I also think, given 
the current climate, having a better MRUnit website is something we should do
but the good news is that this is being worked.

Also I started a thread on graduation, here:

So we can keep track of the progression there too.
Thanks for the poke!
