我试图在我的Windows 10机器上运行Hadoop 3.1.1 . 我修改了所有文件：

  • hdfs-site.xml

  • mapred-site.xml

  • core-site.xml

  • yarn-site.xml

然后，我执行了以下命令：

C:\hadoop-3.1.1\bin> hdfs namenode -format

格式正确运行，因此我指示 C:\hadoop-3.1.1\sbin 执行以下命令：

C:\hadoop-3.1.1\sbin> start-dfs.cmd

命令提示符打开2个新窗口：一个用于datanode，另一个用于namenode .

namenode窗口一直在运行：

datanode给出以下错误：

然后，datanode关闭了！我尝试了几种方法来克服这个错误，但这是我第一次在Windows上安装Hadoop而无法理解下一步该做什么！
