-----------------------------------------------
This issue i tried to reproduce as per steps given above and not faced any
issue. This may be taken care in later versions as this Jira raised long back.
[~Rajkumar Singh] Can you please try from your end and provide more details on
this so that we can work and close this jira. This Jira we can close as of now
and raise a new one if still issue present in latest versions of hive. thank
