Are you volunteering?

Not yet. I think we have a fair bit of what is needed, and it would make
for some interesting uses of the Yahoo!-HP-Intel cirrus testbed.
There was some good work done at U Maryland on Skoll; a tool for
efficiently exploring the configuration space of an application so as to
find defects:

What you need is something like that applied to the hadoop config space
and a set of tests that will shop up problems in a timely manner.
