Vinay Kumar Thota commented on HADOOP-6944:
-------------------------------------------

I agreed your idea, however the local-super-conf.xml file contains different users which serves
for other purposes. Is it ok to impersonate the test jobs with those users instead of using
a user which is specific to testing purpose? 
Actually i thought that there are some users which specific to testing and those users can
utilize for impersonating the test jobs. In the current functionality the testing users are
available in the proxyusers file and we pick them using the getHadoopMultiUsersList methis
and same way we can use the file for gridmix testing also for impersonating the gridmix jobs.
