本篇博客部署是建立在Hadoop高可用基础之上的，关于Hadoop高可用部署请参考：https://www.cnblogs.com/yinzhengjie/p/9070017.html。本篇博客是将Hadoop的高可用配置和zookeeper完全分布式结合使用！
一.分布式协调框架
1>.分布式框架的好处
a>.可靠性：
一个或几个节点的崩溃不会导致整个集群的崩溃。
b>.可伸缩性：
可以通过动态添加主机的方式以及修改少量配置文件，以便提示集群性能。
c>.透明性：
隐藏系统的复杂性，对用户体现为一个单一的应用。
2>.分布式框架的弊端
a>.竞态条件： 一个或多个主机尝试运行一个应用，但是该应用只需要被一个主机所运行。 b>.死锁： 两个进程分别等待对方完成。 c>.不一致性： 数据的部分丢失。
二.Zookeeper简介
1>.Zookeeper的作用
答：为了解决分布式协调框架的一些弊端，就出现了zookeeper软件，它是目前大数据中比较流行的分布式协调框架。
2>.Zookeeper的特色
a>.名字服务：
标识集群中的所有节点，节点能够向其注册并产生唯一标识。
b>.配置管理：
存储配置文件，以便共享。
c>.领袖推选机制：
就是根据其自身的算法推选出leader和follower。
d>.锁和同步服务：
当文件进行修改，会将其进行加锁，防止多用户同时写入。
e>.高有效性数据注册：
一个节点是数据不能超过1M,这个规则是递归的，换句话说，每个节点及其子节点的存储空间大小不能超过1M。
3>.本篇博客部署zookeeper架构图
4>.领袖推选机制介绍
在选举leader节点时，首先会比较事务id，其次比较myid，如果集群中已经有一半机器参加选举，那么次leader就是整个集群中的leader。
为了方便理解，我画了两幅图，便于理解上面的一句话，当事物id一致时推选leader如下：
当事物id不一致时推选leader如下：

四.HDFS高可用配置
1>.启动zookeeper集群（[yinzhengjie@s101 ~]$ xzk.sh start）
启动方式参考："三.zookeeper完全分布式部署",一下是查看集群的zookeeper进程是否启动成功：

五.初学者遇到问题最霸道的解决方案：（这种暴力解决方式适合我这样测试集群中使用，如果你的架构跟我的一样，那么这种方法也适合你）
温馨提示：如果你要格式化集群，最好是将之前的数据目录改名，若你没有删除或修改集群之前的数据目录，格式化后的版本信息仍然是上一次没有格式化的集群版本信息哟！这样很可能导致你的DataNode或者NameNode进程启动不了，或者存在刚刚启动不一会儿进程就挂掉了！
