Jason Lowe commented on YARN-6401:
----------------------------------
Is this something YARN needs to support directly? This seems straightforward
to solve on the application side by wrapping the application launch with a
front-end shell that traps SIGTERM and translates it into the desired signal
for the "real" process.
> terminating signal should be able to specify per application to support
> graceful-stop

> when stop container, first send SIGTERM to the process.
> after a while, send SIGKILL if the process is still alive.
> above process is always the same for any application.
> but, to graceful-stop, sometimes it need to send another signal instead of
> SIGTERM.
> for instance, if apache httpd on slider is running, SIGWINCH should be came
> to stop gracefully.
> the way to stop gracefully is depend on application.
> it will be good if we can define a signal to terminate per application.
