@markap14 thank you for this update. I executed my tests as previously
described and ran into no issues. When disconnecting a node designated as
cluster coordinator from both the UI and on the command line (through
stop/restart) the remaining nodes behaves as expected. It properly displays an
error to the user and nots in logs it's inability to determine a cluster
coordinator. When the coordinator is back online the logs indicate successful
reconnection and communication. Refresh of the screen properly demonstrates the
flow and configured flow (which consists of use of remote process groups
communicating with a standalone nifi node) operate successfully

thank you @markap14 for the quick turnaround on this!
