----------------------------------
Devaraj/Mac, could you also test this patch on your production environment if
you have other testing scripts? I'm testing the script uploaded by Namit in
HIVE-1862 and this patch seems working fine so far.

> 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.
