Review request for hive, Ning Zhang and Siying Dong.
Summary
-------
There are some conditions under which partition descriptions are created in
memory and committed to the metastore despite there being no intermediate or
final finals in that directory (due to dynamic partitioning).
In this change, a check is done to only call loadPartitions that have files in
them.
This addresses bug HIVE-2360.
