> 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.
