Hello devs, I just noticed there is an already merged change [1] that removes per-job mode from the codebase. Regarding that, I would like to mention FLINK-26000 [2] that exists for the same for quite a while, and the reason why we kept the code until now is that, Application Mode does not support SQL job submission. AFAIK that is still the case. FLIP-316 [3] aimed to fill this gap utilizing the SQL Gateway, although it is stale for quite a while.
So if I am not missing something, as it is right now Flink 2.0 will lose the ability of deploying SQL jobs to their dedicated cluster on YARN. Is this something the community considered? I understand that there is more focus around K8s nowadays, but we for example have a platform that operates on YARN, and most of our customers use that, where per-job mode is critical for resource isolation. Looking forward for your thoughts!
