------------------------------------------

             Summary: Hive (and HCatalog) don't allow super-users to add partitions to tables.
                 Key: HIVE-6392
                 URL: https://issues.apache.org/jira/browse/HIVE-6392
             Project: Hive
          Issue Type: Bug
          Components: Authorization
    Affects Versions: 0.12.0, 0.13.0
            Reporter: Mithun Radhakrishnan
            Assignee: Mithun Radhakrishnan


HDFS allows for users to be added to a "supergroup" (identified by the "dfs.permissions.superusergroup" key in hdfs-site.xml). Users in this group are allowed to modify HDFS contents regardless of the path's ogw permissions.

However, Hive's StorageBasedAuthProvider disallows such a superuser from adding partitions to any table that doesn't explicitly grant write permissions to said superuser. This causes the odd scenario where the superuser writes data to a partition-directory (under the table's path), but can't register the appropriate partition.

I have a patch that brings the Metastore's behaviour in line with what the HDFS allows.
