Mark Weghorst updated NIFI-7380: -------------------------------- Attachment: nifi-7380-reproducer.xml > NiFi Stateless does not validate CS correctly > --------------------------------------------- > > Key: NIFI-7380 > URL: https://issues.apache.org/jira/browse/NIFI-7380 > Project: Apache NiFi > Issue Type: Bug > Components: NiFi Stateless > Reporter: Pierre Villard > Assignee: Pierre Villard > Priority: Critical > Labels: nifi-stateless, stateless > Attachments: nifi-7380-reproducer.xml > > Time Spent: 10m > Remaining Estimate: 0h > > When the flow executed with the NiFi Stateless running mode contains a > Controller Service with required properties, it'll fail as it does not take > into account the configuration when performing the validation of the > component. > In *StatelessControllerServiceLookup*, the method > {code:java} > public void enableControllerServices(final VariableRegistry variableRegistry) > {code} > first validates the configured controller services and calls > {code:java} > public Collection<ValidationResult> validate(...){code} > This will create a *StatelessProcessContext* object and a > *StatelessValidationContext* object. Then the method *validate* is called on > the controller service and pass the validation context as argument. It will > go through the properties of the controller service and will retrieve the > configured value of the properties as set in the *StatelessProcessContext* > object. The problem is that the *properties* map in the Stateless Process > Context supposed to contain the configured values is never set. As such, any > required property in a Controller Service is considered as configured with a > null value if there is no default value. This will cause the component > validation to fail and the flow won't be executed. > I opened a PR with a solution that does solve this issue. However I'm not > sure this issue does not affect other scenarios and a better approach could > be necessary (more in line with what is done in NiFi core). -- This message was sent by Atlassian Jira (v8.3.4#803005)
