Hadoop-3.1.2：Datanode 和 Nodemanager 关闭
Hadoop-3.1.2: Datanode and Nodemanager shuts down
我正在尝试在 Windows-10 上安装 Hadoop(3.1.2)，但是数据节点和节点管理器关闭了。
我尝试下载 winutils.exe 和 hadoop.dll 文件并将其放在 bin 目录下。我还尝试以管理员身份更改文件和 运行 的权限。但它没有修复错误
Datanode 关闭错误

我知道这个问题太多了，因为安装 hadoop 的任务很繁琐，但我们将不胜感激任何帮助
我用 these files 覆盖了 bin 目录下的所有文件，一切都按预期开始工作
在C:\BigData\hadoop-2.9.1\etc\hadoop目录中，打开hdfs-site.xml文件并将namenode和datanode位置设置为
/BigData/hadoop-2.9.1/data/namenode
/BigData/hadoop-2.9.1/data/datanode
然后
- 以管理员身份打开cmd。
- 类型和运行
stop-all.cmd
hadoop namenode –formatstart-all.cmd
这里的关键是运行 start-*.cmd 命令从命令-window 以管理员身份打开，而不是以用户身份打开。当然，在此之前，您必须设置这 4 个配置文件和 winutils。
我正在尝试在 Windows-10 上安装 Hadoop(3.1.2)，但是数据节点和节点管理器关闭了。
我尝试下载 winutils.exe 和 hadoop.dll 文件并将其放在 bin 目录下。我还尝试以管理员身份更改文件和 运行 的权限。但它没有修复错误

我知道这个问题太多了，因为安装 hadoop 的任务很繁琐，但我们将不胜感激任何帮助
我用 these files 覆盖了 bin 目录下的所有文件，一切都按预期开始工作
在C:\BigData\hadoop-2.9.1\etc\hadoop目录中，打开hdfs-site.xml文件并将namenode和datanode位置设置为
/BigData/hadoop-2.9.1/data/namenode
/BigData/hadoop-2.9.1/data/datanode
然后
- 以管理员身份打开cmd。
- 类型和运行
stop-all.cmd hadoop namenode –formatstart-all.cmd
这里的关键是运行 start-*.cmd 命令从命令-window 以管理员身份打开，而不是以用户身份打开。当然，在此之前，您必须设置这 4 个配置文件和 winutils。
