Andy Jefferson commented on HIVE-2084: -------------------------------------- "allowNulls" can either be set in metadata (XML,annotation) for the container field or it can default to what the particular "java.util" type does so, for example, HashMap/HashSet/LinkedHashSet/any-type-of-list default to allowNulls=true, and all others default to false currently. Only you know what type is your map > 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.D5685.1.patch, > 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.
