> I have a JsonRecordSetWriter controller service. It depends on a Schema Registry controller service. Both are enabled. Upon restart, the JsonRecordSetWriter service fails to enable, indicating that the Schema Registry service is not enabled. When I look at the Controller Service configuration, though, the Schema Registry service is enabled. So it appears that the JsonRecordSetWriter was attempting to be enabled before the Schema Registry Service finishes enabling.
