问题分析：
根据报错"如果未启用ha，则不得指定共享编辑目录"提示定位到./hdfs-site.xml文件。在hdfs-site.xml文件中配置过两个共享目录，分别是journalnode namenode，查看后发现journalnode.edits多输入一个t
问题解决：
删除多余的t，重新分发hadoop到salve1 slave2节点
再次进行namenode格式化

总结：
在修改配置文件部分一定要细心，namenode格式化过程中报错大多都是配置文件写错了。根据报错找到对应文件进行修改。文章来源地址https://www.toymoban.com/news/detail-851507.html
