> MetaStoreListener and HiveMetaHook both serve as a notification mechanism for metastore-related
events. The former is used by hcat and the latter is by the hbase-storage handler, and invoked
by the client. 
> I propose to merge these interfaces, and extend the MetaStoreListener, to add most of
the on- and pre- methods at the Thrift interface. This way, extending metastore will be easier,
and validation, storage-driver notification, and enforcement can be delegated to individual
listeners. Besides, more functionality can be plugged-in by Hcat at this level.
