Karthik Kambatla commented on HADOOP-8552:
------------------------------------------

Devaraj, thanks for the feedback.

It is both on the client/server side. By server side, I mean for the jobtracker/namenode.
Thanks for pointing the potential compatibility issue, I agree we need to note the incompatibility
in log file change.

> In log4j.properties, hadoop.security.log.file is set to SecurityAuth.audit. In the presence
of multiple users, this can lead to a potential conflict.
> Adding username to the log file would avoid this scenario.
