zkdetect测试代码主要负责发现mesos master leader

1. standalone模式

1.1先启动本地mesos集群：

root@ubuntu:/home/tjy/mesos-0.24.0/build/bin# ./mesos-local.sh --ip=127.0.0.1 --port=5050

1.2然后执行测试代码：

root@ubuntu:/home/tjy/go-ws/src/github.com/mesos/mesos-go/examples/_output# ./zkdetect -masters 127.0.0.1:5050 -log_dir . -v 3

1.3执行结果如下：

root@ubuntu:/home/tjy/go-ws/src/github.com/mesos/mesos-go/examples/_output# cat zkdetect.INFO

2. High Availability模式

2.1 先启动HA模式的mesos集群

2.2 执行测试命令：./zkdetect -masters zk://192.168.1.91:2181/mesos -log_dir . -v 3
