You are not running zkCli.sh without parameters, but you are only telling it about a single server; it thus doesn't have anywhere to fall back when that single node becomes unreachable. Try something like: $ zkCli.sh -server "10.251.0.6:2181,10.251.0.X:2181,10.251.0.Y:2181" where 10.251.0.X and 10.251.0.Y are replaced by the addresses of the other ensemble members. (This is not specific to the "CLI"; other clients also have to be given a "sufficient" connection string to be able to failover. It doesn't *have* to reference the full ensemble, but providing a single member definitely won't cut it.) HTH, -D
