Review comment:
I think this is independent of this question because
`checkAndUpdateConfigMap` should never create a non-existing config map
according to the code. If `getConfigMap()` returns `Optional.empty()` then we
will throw the `FlinkRuntimeException`, retry and end up again receiving an
`Optional.empty()`.
