-------------------------------------------------------------------

                 Key: HADOOP-6770
                 URL: https://issues.apache.org/jira/browse/HADOOP-6770
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 0.20.1
            Reporter: sam rash


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
