Amareshwari Sriramadasu commented on HIVE-1538:
-----------------------------------------------
bq. I think the solution is to collect the operators who are contributing the
predicates for "final candidates of predicare pushdown" and remove them from
the final operator graph.
This does not work as I thought earlier, because all the predicates in the
FilterOperator may not be pushed. We might have to reconstruct the
FilterOperator with un-pushed predicates.
> FilterOperator is applied twice with ppd on.
