[jira] [Created] (NIFI-11392) NiFi does not stop timely when using CRON scheduling

Michael W Moser created NIFI-11392:
--------------------------------------

             Summary: NiFi does not stop timely when using CRON scheduling
                 Key: NIFI-11392
                 URL: https://issues.apache.org/jira/browse/NIFI-11392
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.20.0
            Reporter: Michael W Moser


When using CRON scheduling on at least 1 processor in a flow, and any CRON driven processor has been scheduled at least once, then NiFi does not stop within the graceful.shutdown.seconds period and has to be killed.  If possible it would be nice to clean this up.

I setup GenerateFlowFile with a CRON schedule of "0 * * * * ?".  After it has run once, I stopped NiFi and it was killed after 20 seconds instead of stopping in 2 or 3 seconds.
