title: YARN REST API custom user to run the job instead of dr.who
body: <p>What do I need in order to provide a user that runs this job as? For example when I do <code>hadoop jar ...</code>  - the user logged in is used as the user to submit the job. How can I do the same with YARN REST API?</p>
  
  <p>Thanks for your help. I googled around but the examples and documentation does not talk about it. The job runs as dr.who.</p>
  
  <p>Regards,
