Description

Always reproduced.

On any service, change some setting to be node specific (instead of global to the cluster).
To do so create a config group, switch to it and change some setting to be specific for that group.

Now, stop and delete the service. The configuration is deleted but the group configuration is left behind.

From this moment the log will be full of " Config inconsistency exists: unknown configType=dbks-site" (in my case the service I reproduced it was Ranger KMS).
Any attempt to add a service will get a 500.

The only workaround is going to the DB and manually delete the group configuration from the table confgroupclusterconfigmapping
