Zhang commented on YARN-9384:
-----------------------------
[~qiuliang988], No perfect solution. Now KillApplication can only kill
containers in home subcluster immediately. Containers from secondary
subclusters can continue running for like 10minutes until application in
secondary subclusters become "FAILED".
> FederationInterceptorREST should broadcast KillApplication to all sub clusters

>
> 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.
