-----------------------------------
Summary: Improve startup error messages in log
Key: NIFI-6336
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
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.
