Jason Lowe commented on YARN-3692:
----------------------------------
We cannot change the signature of the existing killApplication method or we
break backwards compatibility. However as [~Naganarasimha] mentioned we can
simply add another method that takes the two arguments instead of one. Then we
can support both the old method for backwards compatibility and the new method
which allows a user-provided diagnostic. I'm not sure we should deprecate the
old method just yet. We can still generate a useful diagnostic message
automatically on the RM side when one is not provided, such as which user from
which host issued the kill command.
> Allow REST API to set a user generated message when killing an application

> Currently YARN's REST API supports killing an application without setting a
> diagnostic message. It would be good to provide that support.
