He Yongqiang commented on HIVE-78:
----------------------------------

I think this jira is just a first step towards a fulfilled security feature. It 
just does the meta-store check to see if a given user be able to issue the 
query or not.
There is no integration with HDFS/MR part. So the file owner and the job 
executer are just the same as now. 
A long term plan is to set up HiveServer.

> Authorization infrastructure for Hive
