> When NiFi elects a new cluster coordinator, the newly elected coordinator starts accepting heartbeats from the cluster nodes. If another cluster coordinator election occurs later which results in the original Node being elected as the cluster coordinator once again, old heartbeat messages exist which will trigger all nodes to be dropped due to their age exceeding the threshold for last received heartbeat.
