--------------------------------------------------------------
Attached PIG-3417_2.patch with these changes:
- key tuple is not flattened, but statistics are
- golden files changed accordingly. TestTezCompiler test passed with these
changes, and no test failed in TestMRCompiler
- added an assert for the output to testSkewJoinWithTuples and added an e2e
test too
We might not even need to have testSkewJoinWithTuples, since the e2e tests now
cover this case. [~rohini] could you please have have a look at the second
version of my patch?

> two relations separately, then full-outer joins them on the grouped columns.
> The test case passes if "using 'skewed'" is removed.
