What I were care about is submit host not driver host and I have built the
spark under trunk and tested in yarn-cluster mode, there is no submit host in
am log (even enable debug). So current platform team still difficult to know
where an application submitted. They even have to check the YARN audit log to
find out where an create operation upon some .sparkStage/files to know the
submit host.
