> This issue was reported by [~kbadani].
> Steps to reproduce this issue:
> * Kdestroy and kinit as 'livy' user
> * Do spark-submit with --proxy-user as 'hrt_1'
> * In the console output, you can see that 'ambari-qa' is trying to
> impersonate as 'hrt_1' and its failing
> * Cancel the running job and do klist again - it will show credentials for
> 'ambari-qa' user and not the 'livy' user with which it was kinited
> {code:java}
