> 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.
> For more background on this proposed change see HCATALOG-237 and https://cwiki.apache.org/confluence/display/HCATALOG/Hcat+Security+Design
