Hi [~aw] could I get a review? Trivial one.

> Issue found when working with the HDFS balancer.
> In {{hadoop_daemon_handler}}, it calls {{hadoop_verify_logdir}} even for the "default"
case which calls {{hadoop_start_daemon}}. {{daemon_outfile}} which specifies the log location
isn't even used here, since the command is being started in the foreground.
> I think we can push the {{hadoop_verify_logdir}} call down into {{hadoop_start_daemon_wrapper}}
instead, which does use the outfile.
