Hi Itamar, You should really run zookeeper on more than one node (typically 3, 5, or 7 is very common). Otherwise, in your case, if the node running your zookeeper servce goes down for any reason, your whole mesos installation would stop working until you bring that node back. Regards, Shuai O

Interesting. I knew I needed to look into ZooKeeper more than I did :-) I don't know what's "distributed mode" in ZooKeeper. I can tell you we use a single host for the master, and configure all machines with "zk://master-host-name:2181/mesos" in /etc/mesos/zk before the mesos services are started
