Daniel Dai commented on PIG-910:
--------------------------------

I discussed with Santhosh, this issue is addressed by PIG-697 phase 5 patch 
(LOJoin patch). PIG-910-1.patch is a temporary solution before LOJoin patch, 
and is not intended to commit.

> PushUpFilter: Filter after skew LOJoin generates an error
