> We see this issue occasionally. The symptom is that when /controller path got
> deleted, the old controller does not resign so we end up having more than one
> controller in the cluster (although the requests from controller with old
> epoch will not be accepted). After checking zookeeper watcher by using wchp,
> it looks the zookeeper session who created the /controller path does not have
> a watcher on /controller. That causes the old controller not resigning.
