> It seems the datanucleus 2.2.3 does a better join in caching. The time it
> takes to get the same set of partition objects takes about 1/4 of the time it
> took for the first time. While with 2.0.3, it took almost the same amount of
> time in the second execution. We should retest the test case mentioned in
> HIVE-1853, HIVE-1862.
