> 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.
