Github user JPercivall commented on the issue:
https://github.com/apache/nifi/pull/689
Reviewing this and came across a state that I'm not if its intended or not.
ncm and 2 node cluster with a flow GenerateFF (primary node only) ->
LogAttribute
set a break point on line 3809 of FlowController.java to cause the primary
node to stop sending heartbeats
after 45 seconds of not receiving heartbeats the NCM disconnects the node
from the cluster
at that time observe that the FFs are no longer getting logged (assume
because the GenerateFF is no longer being scheduled)
Also I cannot access the UI of the node that is disconnected.
> Nodes run "Primary Node Only" processors when disconnected from cluster
