Description

JHS today displays all Job conf properties in Web UI directly. Users may have some credentials or any sensitive information they added to the job conf but do not want to be shown in Web UI. It'd be nice if we can allow users to specify a set of properties which JHS will filter out when Job conf is displayed.
