This looks good to me modulo a few comments! One other thing though, you
should add a unit test for this functionality. Create a test that would result
in a very long running time with the old code (e.g. something where you zip
RDDs together 20-30 times and the original one has some preferred locations),
and add something around it to time that it runs within, say, 5 seconds.
