Add a getAuthorizationProvider to HiveStorageHandler
----------------------------------------------------
Key: HIVE-2768
URL: https://issues.apache.org/jira/browse/HIVE-2768
Project: Hive
Issue Type: Task
Components: HBase Handler
Reporter: Alan Gates
In version 0.92 HBase supports ACLs for tables. In HCatalog, since we delegate
security to the underlying storage layer, we would like to be able to obtain a
HiveAuthorizationProvider specific to a HiveStorageHandler instance. This can
be done by adding a getAuthorizationProvider method to HiveStorageHandler. In
the case where Hive is configured to use the DefaultHiveAuthorizationProvider
this call will return the same default provider, since Hive handles all of the
authorization itself in that case. In the case where it is configured to use
the HCatAuthorizationProvider, it would return an instance specific to the
underlying storage.
