Description

We recently improved the JM deployment deletion mechanism, however it seems like task manager pod deletion can get stuck sometimes for a couple of minutes in native mode if we simply try to delete everything at once.

It speeds up the process and leads to cleaner shutdown if we scale down the JM deployment to 0 (shutting down the JM pods first) and then perform the deletion.
