Haibo Chen commented on MAPREDUCE-6741:
---------------------------------------
Patch uploaded to address Jason's comment. The changes are specifially,
1) values of redacted properties are replaced with a literal string
"*********(redacted)"
2) properties are also redacted from AM UI
3) add the new configuration to mapred-default.xml
4) In JHSEventHandler, a new configuration is copied from the original. In AM
UI, the configuration object is loaded from the HDFS job.xml file every time
the page is loaded, no need to make a copy.
> add MR support to redact job conf properties from JHS

> 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.
