Colin Ma commented on SENTRY-531:
---------------------------------

[~prasadm], is there any hive plugin can access the ObjectStore without 
HiveMetaStoreClient? Both hcatalog and webhcat won't access the ObjectStore 
directly. For the local metastore, authorization in ObjectStore doesn't work, 
but HiveMetaStoreClient can do the authorization for  both local metadata and 
remote metadata. I think we need do the authorization for metadata in 
HiveMetaStoreClient, otherwise, there will be the same source code in 
ObjectStore and HiveMetaStoreClient.

> Add column authorization for metadata read protection
