Push down partition pruning to JDO filtering for a subset of partition
predicates
---------------------------------------------------------------------------------
Key: HIVE-2049
URL: https://issues.apache.org/jira/browse/HIVE-2049
Project: Hive
Issue Type: Sub-task
Reporter: Ning Zhang
Assignee: Ning Zhang
Several tasks:
- expose HiveMetaStoreClient.listPartitionsByFilter() to Hive.java so that
PartitionPruner can use that for certain partition predicates.
- figure out a safe subset of partition predicates that can be pushed down to
JDO filtering.
By my initial testing for the 2nd part is equality queries with AND/OR can be
pushed down and return correct results. However range queries on partition
columns gave NPE by the JDO execute() function. This might be a bug in the JDO
query string itself, but we need to figure it out and heavily test all cases.
