什么是supergroup和 superuser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。引用文献
