--------------------------------
Hello [~botong], Thank you every much, the patch is helpful to us.
Now, I have a problem. When the diagnostics of application contains illegal
characters, the XML is returned by
http://rm-http-address:port/ws/v1/cluster/apps which contains illegal
characters. Router couldn't parse this XML, and caused GPG delete all
applications in the federation state store. Could you please give us some
suggestions on this problem?

> In Federation, we need a cleanup service for StateStore as well as Yarn
> Registry. For the former, we need to remove old application records. For the
> latter, failed and killed applications might leave records in the Yarn
> Registry (see YARN-6128). We plan to do both cleanup work in
> ApplicationCleaner in GPG
