Problem with Internal Classes for a TableMap / TableReduce in 0.2.0
Heads up for anyone else running into this issue. I found that you cannot
use internal classes for your Map or Reduce class if you're extending
TableMap/TableReduce. If you try, you get a NoSuchMethodException:
TestTableMapReduce$Map.<init>()
Not sure why, but I suspect it has to do with initJob (a static method which
isn't content being a part of internal non-static class).

Maybe we are not talking about the same thing after all.
Oh well. That would be my mistake then.

Hmmm... It was working in 0.1.3 for me. It was when I moved to 0.2.0 that it
stopped.

Just to add, this isn't a 0.2 problem. This was my very first gotcha, back with 0.1.0.
