Description

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.
