> URL: https://issues.apache.org/jira/browse/NIFI-6336
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Configuration, Core Framework
> Affects Versions: 1.9.2
> Reporter: Andy LoPresto
> Assignee: M Tien
> Priority: Major
> Labels: configuration, error, log, troubleshooting
> Fix For: 1.11.0

> We frequently have users who encounter startup errors due to configuration
> but can't understand the error messages to resolve the issues on their own.
> Improving the specific error messages, and providing context around them,
> would help users diagnose their own issues and supporters/community members
> offer better, more targeted solutions-oriented advice rather than having to
> ask investigatory questions and wait for synchronous conversations.
> Example issue where one of the ports (not clear from error messages) isn't
> specified in a cluster {{nifi.properties}} configuration file so the
> application fails to start up (happened during 1.7.1 to 1.9.2 migration).
> {code}
> Caused by: org.springframework.beans.factory.BeanCreationException: Error
> creating bean with name 'flowService': FactoryBean threw exception on object
> creation; nested exception is
> org.springframework.beans.factory.BeanCreationException: Error creating bean
> with name 'flowController' defined in class path resource [nifi-context.xml]:
> Cannot resolve reference to bean 'clusterCoordinator' while setting bean
> property 'clusterCoordinator'; nested exception is
> org.springframework.beans.factory.BeanCreationException: Error creating bean
> with name 'clusterCoordinator': FactoryBean threw exception on object
> creation; nested exception is java.lang.IllegalArgumentException: Port must
> be inclusively in the range [1, 65535]. Port given: 0
> {code}
> At least including the {{nifi.properties}} property/key in this error would
> make the issue and solution much clearer.
