Upgrade datanucleus to from 2.0.3 to 2.2.3
------------------------------------------
Key: HIVE-2084
URL: https://issues.apache.org/jira/browse/HIVE-2084
Project: Hive
Issue Type: Improvement
Reporter: Ning Zhang
Assignee: Ning Zhang
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.
