> tested with security on, no filters defined for httpserver, job acls set so that only I could view/modify the job.  Then went to the web ui to app master and job history server and both allowed me to view the job details.  The webui shows the user "webuser".   The RM properly rejected my request although it was using user "Dr.Who".
