什么是supergroupsuperuser在 Hadoop/HDFS 中?

最佳答案

super 用户

基于Hadoop official documentation :

The super-user is the user with the same identity as the name node process itself. Loosely, if you started the name node, then you are the super-user. The super-user can do anything in that permissions checks never fail for the super-user.



super 群

Supergroup 是 super 用户组。该组用于确保 Hadoop 客户端具有 super 用户访问权限。可以使用 dfs.permissions.superusergroup 进行配置 core-site.xml 中的属性(property)文件。
