Sorry if this question has been asked before but how does Rancher handle Zookeeper failures. Is there some kind of monitoring mechanism (like Exhibitor) or self-healing mechanism. Say nodes fail (1 node fails in a 3 node quorum) or for some reason the entire quorum gets botched. How would Rancher deal with this? What would be the steps to take to recover. I guess this is more Mesos based since it relies heavily on Zookeeper for HA. I am also very interested to know how this works for the other cluster managers (Kubernetes and Swarm), not too familiar with their semantics.
