Description

A controller service can be enabled but not working. For example, say your flow uses a ConvertRecord processor. Say one or both of the record reader/writers used in the processor references the HortonworksSchemaRegistry controller service. The Hortonworks Registry that the controller service points to could go down. But in this situation the controller service itself is still enabled and there are no warnings given to the user.
