为了配置完全分布式的hbase需要有一个zookeeper集群。一般来说为了防止脑裂，zk集群需要时奇数个节点，因此本次实验使用三台机器：node93、node94、node95。

# node93

# node94
echo 2 > /media/moosefs/zookeeper/myid
# node95
echo 3 > /media/moosefs/zookeeper/myid

启动ZK
启动前预先将zk安装目录安装到各个节点并同步配置文件，注意myid文件每台机子内容不一样哦
在每台机子上启动zookeeper

可以看到node93，node95是follower，node94是leader
