Review request for hive and Paul Yang.
Summary
-------
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.
This addresses bug HIVE-2213.
https://issues.apache.org/jira/browse/HIVE-2213
