var manatee = require('node-manatee');var client = manatee.createClient({ "path": "/manatee/1", "zk": { "connectTimeout": 2000, "servers": [{ "host": "172.27.10.97", "port": 2181 }, { "host": "172.27.10.90", "port": 2181 }, { "host": "172.27.10.101", "port": 2181 }], "timeout": 20000 }});client.once('ready', function () { console.log('manatee client ready');});client.on('topology', function (urls) { console.log({urls: urls}, 'topology changed');});client.on('error', function (err) { console.error({err: err}, 'got client error');});
