Jim Brennan commented on YARN-7848:
-----------------------------------
I think I agree with [~eyang] on the use of {{-f}}. By the time we are trying
to remove the container, we have already tried to kill the process and stop the
container, so I don't think there is any danger in using the -f option, and it
may succeed in cases where it otherwise doesn't now. I can't think of anything
bad that would happen by using the force option every time in our use cases.

> After the addition of YARN-5366, containers will get removed after a certain
> debug delay. However, this is a one-time effort. If the removal fails for
> whatever reason, the container will persist. We need to add a mechanism for a
> forced removal of those containers.
