Matthew Clarke commented on NIFI-483:
-------------------------------------

Could we add another scheduling strategy to solve this problem?  On Primary Node (CRON)?  The Cron strategy is not affected by restarts.

> 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.
