"The fix is to persist the ATS v1.0 configs even if ATS is not present. The service checks will still fail, but the user can then add ATS after EU is done."
Are we ok with service checks failing during EU or this a temporary fix for now? Can we do something to notify the user and skip service checks for Hive in EU in this setup?
