Thank you raising this issue. Scenario does make sense to me in testing cluster.
But in production scenario may be not . Existing may be enough.

{code}
 -kill <Application ID>                   Kills the application. Set of
                                          applications can be provided
                                          separated with space
{code}

More than cluster level application kill ,will it be better in have kill per 
queue. And if "root" queue is specified will kill all apps in cluster.

> If we want to kill all running applications then currently we need to give 
> all application Id's. So instead we can have a command which can kill all 
> applications. 
> Command would be *yarn application -killall*
