    it('client for', function(done) {
        this.timeout(100000000);
        var options = {zkservers:'localhost:6388,localhost:2181'};
        var client = new ClusterClient(options);
        client.init();
        client.on('error', function(err) {
            console.error('err:%s', err);
            done();
        });

        client.on('connect', function(client) {
            var count = 0;
            function batch() {
                setTimeout(function() {
                    client.clientFor(count, function(err, c) {
                        // console.log('%s:%d set %d %d', c.host, c.port, count, count);
