Yang Wang commented on FLINK-27337:
-----------------------------------
I lean to not propagate the deletion to all the session jobs. It may cause some
serious problems in production environment. What in my mind is let the webhook
to prevent the deletion and print the warning message to users. Or at least we
could do this in the {{{}SessionReconciler#shutdow{}}}.
I am not pretty sure whether we should also prevent the upgrade when there are
running jobs.
