---------------------------------

             Summary: Updating parameter used by running processor can result in the processor
not restarting because it doesn't wait for validation to complete.
                 Key: NIFI-6735
                 URL: https://issues.apache.org/jira/browse/NIFI-6735
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.10.0
            Reporter: Rob Fellows
            Assignee: Rob Fellows
         Attachments: Processor fails to restart.png

There is a timing issue when updating a parameter that is referenced by a running processor.
Updating the parameter context stops the processor and tries to restart it. However, validation
of the processor might not be complete by the time it is attempted to be restarted and you
can get an error (see attached image) and the processor does not restart automatically.
