[jira] [Commented] (YARN-9384) FederationInterceptorREST should
broadcast KillApplication to all sub clusters
[ https://issues.apache.org/jira/browse/YARN-9384?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16896096#comment-16896096 ]

--------------------------------
Hi [~mzhang], how do you solve this problem when executing "yarn application -kill"?

> Today KillApplication request from user client only goes to home cluster. As a result the containers in secondary clusters continue processing for 10~15 minutes (UAM heartbeat timeout).
> This is not an favorable user experience especially when user has a streaming job and sometime needs to restart it (like updating config or resources). In this case, containers created by new job and old job can run at the same time.
