Hong Tang commented on MAPREDUCE-1605:
--------------------------------------

MAPREDUCE-1376 requires Gridmix3 being launched by a regular "super user" that 
has properly authenticated with Kerberos server. In this jira, we would like to 
allow Gridmix3 to be launched by a headless user authenticated with Kerberos 
through keytab.

The title is a bit misleading, what we want is to launch gridmix3 through a 
headless user, whether jobs are submitted as real user or headless users is 
probably irrelevant.

> Support multiple headless users to be able to submit job via gridmix v3
