             Summary: Update HiveMetastore authorization to enable use of 
HiveAuthorizer implementation
                 Key: HIVE-21753
                 URL: https://issues.apache.org/jira/browse/HIVE-21753
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 3.1.2
            Reporter: Ramesh Mani


Description: Currently HMS supports authorization using 
StorageBasedAuthorizationProvider which relies on permissions at filesystem – 
like HDFS. Hive supports a pluggable authorization interface, and multiple 
authorizer implementations (like SQLStd, Ranger, Sentry) are available to 
authorizer access in Hive. Extending HiveMetastore to use the same 
authorization interface as Hive will enable use of pluggable authorization 
implementations; and will result in consistent authorization across Hive, HMS 
and other services that use HMS (like Spark).
