[jira] [Commented] (YARN-7599) [GPG] ApplicationCleaner in Global
Policy Generator
[ https://issues.apache.org/jira/browse/YARN-7599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16936320#comment-16936320 ]

--------------------------------
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
