Allen Wittenauer commented on HADOOP-13595:
-------------------------------------------
A non-privileged user can run diskbalancer and mover? That's... surprising.
Also, mover has the HADOOP_SUBCMD_SUPPORTDAEMONIZATION set to "true" flag...
which means it is technically a daemon.
> Rework hadoop_usage to be broken up by clients/daemons/etc.

> Part of the feedback from HADOOP-13341 was that it wasn't obvious what was a
> client and what was a daemon. Reworking the hadoop_usage output so that it
> is obvious helps fix this issue.
