Owen O'Malley resolved HADOOP-6770.

    Resolution: Won't Fix

The code no longer uses the external 'whoami' command. It uses the JAAS interface.

> at present, we fork and use whoami to get the current username.  we can avoid the fork(which
can be slow) and user System.getProperty("user.name") which is set by the jvm
