问题描述
在配置Hadoop HA（High Available）高可用的时候，配置文件修改完毕，进行namenode格式化的时候发生的错误。

问题分析
NameNode不能正常运行，不是配置错了，而是不能连接上JournalNode。
分析日志记录： NameNode作为JournalNode的客户端发起连接请求，但是失败了，然后NameNode又向其他节点依次发起了请求都失败了，直至到了最大重试次数。通过实验知道，先启动JournalNode或者再次启动NameNode就可以了，说明JournalNode并没有准备好,而NameNode已经用完了所有重试次数。

原因分析
目前暂不清楚，请大佬指教...

解决办法
经过查询资料等途径，最终使用了先开启journalnode 的方法决绝的问题。
在所有包含journalnode 的节点中先开启journalnode，再进行格式化。

hadoop-daemon.sh start journalnode
