Nandakumar commented on HIVE-15579:
-----------------------------------

Not able to edit the jira to add release note. (guess I don't have permission)

Content to be added as part of release note:
{quote} Using HADOOP_PROXY_USER a superuser can access hive through hive cli on 
behalf of another user.
To use this feature, export HADOOP_PROXY_USER with the user that has to be 
proxied and start hive cli.

The HADOOP_PROXY_USER can be set either in system environmental variable or in 
system property {quote}

> Support HADOOP_PROXY_USER for secure impersonation in hive metastore client
