Description
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.
