gyfora opened a new pull request, #791:
URL: https://github.com/apache/flink-kubernetes-operator/pull/791
## What is the purpose of the change
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.
