I see. Thanks for the clarification.
That's a valid point. You're right that I can't 100% guarantee whether the
kill was executed or not. But as long as job flows are designed to be
idempotent, that shouldn't really matter. Production jobs that run in cloud
like ours follow the best practice anyway.
The main motivation for me to add this option was to free up cluster
resources as much as possible on a best-effort basis.
