Subject [jira] [Commented] (MAPREDUCE-6741) add JHS support to hide job conf properties from Web UI
Date Fri, 22 Jul 2016 19:44:20 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6741?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15390092#comment-15390092

Haibo Chen commented on MAPREDUCE-6741:

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.
