> Currently, when handling {{{}forceKillApplication{}}}, we follow this logic:
> first, we kill the Application in the {{{}HomeSubCluster{}}}, and then kill
> the Applications in the other subclusters. This approach can lead to an issue
> where, if a subcluster does not have the Application, the subcluster's RM
> throws an "application not exists in RM" exception. In this case, we can
> safely ignore the exception as it does not impact our normal processing flow.
