Kiran Kumar Kolli commented on HIVE-16086:
------------------------------------------

[~vihangk1] its yes and no. Yes from enumeration perspective but No from the end result perspective.
FindUnknownPartition returns Set which de-dupes them so end-result is same. With-out this
fix, enumeration will do waster work exponentially but not the end-result.
