Rohini Palaniswamy commented on PIG-4902:
-----------------------------------------

bq. The vertex output data size is larger since DistinctCombiner does not do column projection.
   Did not understand why the data size is larger. Distinct is on the whole alias right? What column projection are we talking about?. I can revisit  PIG-4884 if there is data size increase and try fixing that.

> Saw UT failures in TestPigScriptParser and TestTezGraceParallelism on 0.16 branch and trunk. 
> TestTezGraceParallelism failures are introduced by PIG-4884. The vertex output data size is larger since DistinctCombiner does not do column projection. Also due to the plan change, the vertex name also changed.
