HIVE-1644.9.patch
Added task relabeling to the addDependentTask method in Task.java. It still
seems like we're generating our re-entrant index query twice. Yonqiang, I
think we end up calling IndexWhereTaskDispatcher.dispatch twice as often as we
want, which causes us to process the operator tree twice.
> use filter pushdown for automatically accessing indexes
