Mark Payne commented on NIFI-483:
---------------------------------
I think the solution here is not to add a new Scheduling Strategy but rather to
divorce the concepts of "Primary Node Only" and the Scheduling Strategy. I.e.,
we should have 3 scheduling strategies: Timer Driven, Event Driven, Cron Driven
- and Primary Node Only as a separate concern.
> Automatically elect a new primary node to allow rolling restarts

> Project: Apache NiFi
> Issue Type: Sub-task
> 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.
