[jira] [Created] (NIFI-483) Automatically elect a new primary node
to allow rolling restarts
Ricky Saltzer created NIFI-483:
----------------------------------
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.
