Paul Yang commented on HIVE-2213:
---------------------------------
If get_partitions_ps_with_auth() was not correct before, then we should fix the
method to produce the correct behavior. Ideally, it should have been done in a
separate JIRA, but it should be okay to include in this one.
+1 looks good though, will test and commit.

> If a table has a large number of partitions, get_partition_names_ps() make
> take a long time to execute, because we get all of the partition names from
> the database. This is not very memory efficient, and the operation can be
> pushed down to the JDO layer without getting all of the names first.
