Review Comment:
Because `SessionHiveMetaStoreClient` extends `HiveMetaStoreClient`, it
should also check null for part_vals like `HiveMetaStoreClient`, and
`PartitionTree` should support empty or even null part_vals like metastore
server in my opinion.
Otherwise it would cause the inconsistent test results in
`TestListPartitions` for `HiveMetaStoreClient` and
`SessionHiveMetaStoreClient`, for example `testListPartitionsByValuesNoVals()`.
The master branch mark this test expect `MetaException`, but actually it should
return all partitions for empty part_vals. It could pass the test in master
because it throws `MetaException` when making part name for empty partVals in
`getNumPartitionsByPs`, which should be a bug in implement this method.
