             Summary: Automatically elect a new primary node to allow rolling restarts
                 Key: NIFI-483
                 URL: https://issues.apache.org/jira/browse/NIFI-483
             Project: Apache NiFi
          Issue Type: New Feature
            Reporter: Ricky Saltzer


In a clustered environment, if you restart the primary node's NiFi instance, all of the processors
scheduled on "Primary Node" will automatically be re-executed on start up. This is a problem
if you require a processor to only execute once per day, for example.  

To get around this, you must manually promote a different node to primary before restarting
it. I think it would be a worthwhile feature to have the primary node automatically elect
another node primary if it's being restarted.
