Santhosh Srinivasan updated PIG-646:

    Attachment: PIG-646.patch

Attached patch fixes the issue with reporting progress in Distinct.java and 
also sets up the reporter correctly in PigCombiner.java and 
PigMapReduce.ReduceWithComparator. In addition there are unit test cases in 
TestBuiltin.java and TestEvalPipeline.java

All unit tests pass.
