Review request for pig, Cheolsoo Park, Daniel Dai, and Rohini Palaniswamy.
Bugs: PIG-3527
https://issues.apache.org/jira/browse/PIG-3527
Repository: pig-git
Description
-------
Adds support for multiple LogicalInputs to the PigProcessor. This is done by
adding a new TezLoad interface which PhysicalOperators may implement. On the
backend, any operators implementing this interface will have the LogicalInput
attached to them. 2 implementations are included:
* POSimpleTezLoad which consumes a single MRInput
* POShuffleTezLoad which consumes one or more ShuffledMergedInputs.
The POShuffleTezLoad does a k-way merge of the shuffle inputs to package for
the operator pipeline. This required a change to the comparators used so that
the sort order remained consistent. There is also a fix to POForEach where it
was using the incorrect status code for signaling (although it produced the
same end result in the MR pipeline).

Testing
-------
Manual testing and an e2e test has been added. Because of the comparator
change, some of the tests fail because of bag ordering.
Thanks,
Mark Wagner
