Phabricator updated HIVE-2084:
------------------------------
Attachment: HIVE-2084.D2397.1.patch
khorgath requested code review of "HIVE-2084 [jira] Upgrade datanucleus from
2.0.3 to 3.0.1".
Reviewers: JIRA
Updated HIVE-2084 to work off DataNucleus release 3.0.8
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.
TEST PLAN
existing tests (this is a library dep upgrade)
