> In the mapreduce examples driver, you can run TeraGen, TeraSort, and TeraValidate.  To my surprise, TeraChecksum wasn't included in the examples driver.  I think it'd be nice to include.  It can be used to compare the checksum of the input & output.  It's worth noting that TeraValidate calculates the checksum as well.
> Patch to be posted shortly.  I tested against 2.7.1 branch but couldn't against master.  I am including patches for both.  Patch also includes TeraChecksum test case addition.
