--------------------------------
Summary: Controller Service failing to enabled because the service
it depends on is not fully enabled on nifi restart
Key: NIFI-3972
URL: https://issues.apache.org/jira/browse/NIFI-3972
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
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.
