Joseph Witt updated NIFI-1696:
------------------------------
    Description: 
The scenario:
- 3 node cluster
- node 'NodeA' is primary and running a processor 'ProcP1' set to event driven 
scheduling
- 'ProcP1' wasn't working due to a config issue but there were a few events on 
its input queues.
- restarted node 'NodeA' after fixing config issue.
- No new events had come in but those events were sitting there.

Result: The 'ProcP1' appears to be in scheduled state but does not get 
scheduled to run - perhaps because no new event triggered it?  Seems like 
perhaps we're not checking if there are already events at restart?  Stopping 
and starting 'ProcP1' then resulted in things going back to normal.

It is not obvious to me how to recreate this in a repeatable way.

The scenario:
- 3 node cluster
- node 'NodeA' is primary and running a processor 'ProcP1' set to event driven 
scheduling on primary node only.
- restarted node 'NodeA'

Result: The 'ProcP1' appears to be in scheduled state but does not get 
scheduled to run.  Stopping and starting 'ProcP1' then resulted in things going 
back to normal.  Seems like a logic flaw must exist for such a case.  Will try 
to recreate on another cluster to be sure.
