             Summary: Keep processors invalid while referenced Controller Services are Enabling
                 Key: NIFI-8069
                 URL: https://issues.apache.org/jira/browse/NIFI-8069
             Project: Apache NiFi
          Issue Type: Improvement
            Reporter: Matt Burgess


Historically, we have allowed processors to be marked as valid while any referenced Controller Services are enabling. This was to avoid a race condition where the processor was being validated while its controller services were still enabling at startup, which would cause the processor to be stopped even after the CS enabled. However this means a processor can be started and will immediately fail at runtime (not at validation time) if the CS has not finished enabling.

Since then there have been improvements to the startup sequence. Now, if you start an invalid processor, the processor still knows that it's meant to be running and as soon as it becomes valid, it will start. This Jira proposes to mark a processor invalid if the CS is enabling.
