Subject Re: Exceptions in integration test cases

In the context of that test (PCollectionGetSizeIT), the EOFException is
expected-- there isn't any data to read b/c the file is empty. We could
change up the impl to throw a CrunchRuntimeException instead.

For the cogroup test, that sounds suspiciously like a deep copy issue.
Gabriel is the most knowledgable person to ask, he always fixes my deep
copy errors. :)
