Cheolsoo Park commented on PIG-3743:
------------------------------------
In addition, can we fix the skew first so that I can benchmark POValueOuputTez
vs POLocalRearrangeTez? I'd like to measure the impacts of two changes
separately-
# VertexGroup change
# POValueOutputTez
With the skew fix, I can measure #1 isolated. Overnight I was running the same
script that I used before and seeing a perf regression. I'd like to understand
it better. Thanks!
> Use VertexGroup and Alias vertex for union
