Here I have tried to  kill 3 apps (1 running, 1 finished and 1 invalid). As per latest patch,
we can get the exact error as {{Application with id 'application_1452608662572_0008' doesn't
exist in RM.}}
Will this be fine here?

bq.I was just pointing out that as it is coded today users can add other options along with
the kill option that are not supported, or potentially nonsensical like movetoqueu

Yes I agree with this part, its not vulnerable to have some other co-options along with kill.
More validation can be added and it can be ensured that {{kill}} will be an option which cannot
be a sub-options with other commands.

> Currently we cannot pass multiple applications to "yarn application -kill" command. The
command should take multiple application ids at the same time. 
> Each entries should be separated with whitespace like:
> {code}
> yarn application -kill application_1234_0001 application_1234_0007 application_1234_0012
> {code}
