Subject [jira] [Commented] (YARN-4529) Yarn CLI killing applications in batch
Date Wed, 30 Dec 2015 15:10:49 GMT

Naganarasimha G R commented on YARN-4529:

Hi [~linyiqun],
Seems like a usefull feature, but few thoughts/queries,
* this is done as part of Application CLI, but a given user might not have rights to all apps
so would it be better to keep this as part of admin cli ?
* Whether its good to fetch all the app reports to client and then kill, instead would it
be better to get it done in the server ? so that REST can also benifit of it ?
* Whether it would be good to supply a queue name ? and kill all the applications of it and
its children ?

> 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}
