[jira] [Comment Edited] (YARN-7848) Force removal of docker
containers that do not get removed on first try
[ https://issues.apache.org/jira/browse/YARN-7848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16798427#comment-16798427 ]

[~ebadger] {quote}Additionally, how would this work with debug-delay? If I want my image to stick around for awhile (or indefinitely) so that I can debug them, how will that co-exist with this periodic pruning?{quote}
I don't have good answers for system admin allowing image dump to stick around forever. The clean up thread is optional and configurable. The scheduling can be based on debug-delay to ensure image is being kept for debug delay window. This will only delete containers stuck in Created/Exited states after passing maximum of 2x debug-delay window.

> 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.
