zhoukang commented on YARN-9931:
--------------------------------
The background is that in our production cluster we have many Applications and
framework.
We always encountered problem that the container was killed and we have no
information about the operation which the container was doing.
Add a shutdown hook may be unfriendly to the users. And add a feature in yarn
will make the troubleshooting more efficient. [~epayne]
Thanks!

> Like node health check script. We can add a pre-kill script which run before

> For example we can save the thread dump before kill the container, which is
> helpful for troubleshooting.
