[jira] [Comment Edited] (MAPREDUCE-6741) add JHS support to hide
job conf properties from Web UI
[ https://issues.apache.org/jira/browse/MAPREDUCE-6741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15390092#comment-15390092 ]

Good point! I have not thought about updating the jobconf file in HDFS. A question that may or may not be relevant to this. I notice that for every job there are always two job conf files. One file, named job.xml, is submitted by the client and localized as task container resource. The other, named $(jobid)_conf.xml, is created by JobHistoryEventHandler and loaded by JHS. Any particular reason why we have two files lying around for one job?

> 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.
