Joseph Percivall commented on NIFI-2605:
----------------------------------------
Hey [~arpitgupta] and [~markap14], I think there has been some
miscommunication. This ticket seems to be about when a cluster is restarting as
a whole with one node having and un-inheritable flow and is potentially a
duplicate of NIFI-1966[1].
Mark's PR addresses the issue where the cluster is in a state of no leader
elected and a new node joins the cluster. In this event (before Mark's change)
there is the chance that the new node becomes the Cluster Coordinator and kicks
out all the other nodes.
If this seems correct to you two, I'd suggest closing this as a duplicate of
NIFI-1966 and opening a new Jira for the issue Mark is fixing.
