Description
For long running instances and clusters, it's sometimes required to switch out custom NARs for new or updated processors. Currently, when you restart a NiFI instance, processors that are on a timer driven schedule (e.g. 1 day, 1 week) are executed, regardless of their schedule. This can be problematic if you're dealing with datasets that shouldn't be pulled out of schedule.
It would be nice to have a rolling restart, or a refresh ability to load in new NARs without re-executing all of the processors on the system. We could take this one step further and have all processor schedules persisted somewhere, and is read on start up.
