Andy Jefferson commented on HIVE-2084: -------------------------------------- @Carl, http://datanucleus.svn.sourceforge.net/viewvc/datanucleus/test/accessplatform/trunk/test.jdo.datastore/src/test/org/datanucleus/tests/types/SCOMapTests.java?revision=15499&content-type=text%2Fplain look for "checkPutNullValues". Always has passed for me since we started supporting null map values (2 or 3 years ago at a guess), most recently with datanucleus-core-3.1.2, datanucleus-api-jdo-3.1.2, datanucleus-rdbms-3.1.1. Since your problem description provides no information of the circumstances (such as log entries, persistence code etc) then cannot speculate as to what you have > Upgrade datanucleus from 2.0.3 to 3.0.1 > --------------------------------------- > > Key: HIVE-2084 > URL: https://issues.apache.org/jira/browse/HIVE-2084 > Project: Hive > Issue Type: Improvement > Components: Metastore > Reporter: Ning Zhang > Assignee: Sushanth Sowmyan > Labels: datanucleus > Attachments: ASF.LICENSE.NOT.GRANTED--HIVE-2084.D2397.1.patch, > HIVE-2084.1.patch.txt, HIVE-2084.2.patch.txt, HIVE-2084.patch > > > 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. -- This message is automatically generated by JIRA.
