cwsteinbach has commented on the revision "HIVE-2720 [jira] Merge
MetaStoreListener and HiveMetaHook interfaces".
What effect will these changes have on StorageHandlers that were compiled
against older versions of Hive. Will they still work, or will they have to be
recompiled?

>
> 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.
