Naganarasimha G R commented on YARN-4529:
-----------------------------------------

IMO both are usefull and required, if i want to kill all accepted applications, 
i need not first get the list of accepted applications and then individually 
pass one by one (single or multiple params) in the CLI.. and vice versa i need 
not run the kill cli command multiple times if i have a bunch of application 
ids which i want to kill. Thoughts ?

But at the same time i feel above 3 points which i have mentioned can also be 
considered, thoughts ?

> We have not a good way to kill applications conveniently when starting some 
> apps unexpected. At present, we have to kill them one by one. We can add some 
> kill command that can kill apps in batch, like these:
> {code}
> -killByAppStates <States>       The states of application that will be killed.
> -killByUser <User name>         Kill running-state applications of specific 
> user.
> {code}
