He Yongqiang commented on HIVE-1644:
------------------------------------
You have the list of partitions for the original table, and you just need to
found out those partition names exists or not on the index table. So with
"getParitionByName()" (pls check the code to find out the exact name) should
work.
> use filter pushdown for automatically accessing indexes
