> I have created two users user 'unni' and user 'sachin'. user unni created a table 'test3' so that user sachin cannot view that table. But user sachin is able to grant all permission to the table test3.
> I have set 
> 1)hive.security.authorization.enabled=true(in hive-site.xml)
> 2)dfs.permissions=true(in hdfs-site.xml)
> 3)dfs.permissions.supergroup=supergroup(in hdfs-site.xml)
> User sachin and user unni are in supergroup group.
> The user sachin is even able to revoke all permissions from the owner of the table user unni.
