The problem with this proposal is that until HiveMetaStoreClient is a
public API, HCatalog has just as little right to integrate with it directly
as any other third-party. I think the best solution is to invest the time
required to make HiveMetaStoreClient a public API, or to wrap
HiveMetaStoreClient with HiveMetaStoreClient2 and make that a public API
(we'll probably need to take the latter approach since HiveMetastoreClient
currently exposes raw Thrift types).
I filed HIVE-3280 to track this task.
