> In JobClient line 530, we have
> {code}
> String user = System.getProperty("user.name");
> job.setUser(user != null ? user : "Dr Who");
> {code}
> Since a ugi is already obtained in the earlier codes, we should get the username from
ugi, not System.getProperty("user.name").  Also, Exception should be thrown if the username
is null, instead of using a default.
