Peter Vary commented on HIVE-19783:
-----------------------------------
Added review board link: [https://reviews.apache.org/r/67485/]
The patch does the following:
* Adds a new getPartitionLocations method to the RawStore interface.
** Implements getPartitionLocations in ObjectStore using JDQL.
** Implements getPartitionLocations in CachedObjectStore by calling
rawStore.getPartitionLocations (so big tables with many partitions will not
cause problem even if they cannot fit into memory)
* Modifies dropPartitionsAndGetLocations:
** Instead of querying every partition data. Query only the locations using
the new interface method
** Removes partKeys parameter which become unnecessary
[~vihangk1]: Could you please review?
Thanks,
Peter

> Create a RawStore method to retrieve only the locations.
