Eric Badger commented on YARN-7848:
-----------------------------------

bq. Changing this can have dicey outcome and not backward compatible. I am 
likely to have to use cmd file serialization structure to pass the force option 
from Java to container-executor for safety reasons.

Yea that makes sense. I thought we were already using the .cmd file with 
remove-docker-container. Ok, given that reasoning I'm alright keeping the Java 
code as it is and making the code changes all in the container-executor.

> 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.
