zhoukang commented on YARN-9931:
--------------------------------
Thanks [~epayne]I think the command line is used for given container?
what i want to do in this jira is that, we want run a script for each
container(killed by nodemanager).
Since in the production cluster there will always have many containers killed
by rm or am, save some useful information will be helpful.
Thanks [~tangzhankun]this is not for debugging why the container was killed, it
is for debugging what was doing when the container being killed by rm or am.
I have a patch, since we have used this feature in our production for a long
time.

> 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.
