本文解决Hadoop namenode格式化时遇到的ERRORconf.Configuration:errorparsing问题，详细介绍了错误产生的原因及解决方案，指出使用不当的XML注释格式会导致配置文件解析失败。

关于Hadoop进行namenode格式化时ERROR conf.Configuration: error parsing conf xxx.xml错误的问题

在这里插入图片描述
在配置完core-default.xml, mapred-site.xml,hdfs-default等配置文件后，主机格式化namenode时，报错ERROR conf.Configuration: error parsing conf core-default.xml，搞了半天才找到原因，原来是在编辑 .xml文档时，我是在笔记本打开下编辑的，用了<!----->注释导致格式不正确才报错的，直接在虚拟机里或者Xshell下用英文的<!–>注释就好了，或者直接手动删掉注释即可解决。

好的，我现在需要帮助用户解决Hadoop的yarn-site.xml配置文件中的解析错误，具体是关于注释里出现'--'的问题。用户提到错误信息是“'--' not allowed in comment (missing '>'?)”，并且使用的是Hadoop 3.2.4版本。 ...

namenode格式化出现IO错误
Tankcheng的博客

问题提出 在进行节点格式化的时候遇到了这个问题： （如果第二次操作就会从create 变成 remove，即覆盖） 究其根本，是权限不够的原因。 尽管网上讨论这个问题的帖子很多，但是绝大部分并不能解决我的问题。大部分的做法是提升hadoop文件夹的权限等级，但是我发现我已经将hadoop的权限提高了呀！ 那我就试试root权限进行操作，结果是没有问题的，节点格式化能够正常进行并且successful了。但是到了启动伪分布模式的时候，让我输入root localhost 的密码，但是我怎么输密码都是拒绝访问
