Hadoop's rights management is much like Linux, with users, user groups, and Hadoop providing rights management commands, mainly including:
chmod [-R] Mode file ... Only the owner or Superuser of the file has permission to change the file mode. CHGRP [-R] group file ... Users who use the CHGRP command must belong to a specific group and are the owner of the file, or the user is a superuser. chown [-R] [owner][:[Group]] file ... The owner of the file can only be changed by the super user. ls file ... lsr file ... The output format has been adjusted to show the owner, group, and mode.
These commands, if they're familiar with Linux, they'll never be strangers.
chmod: Modify file permissions, including owner permissions, user group permissions, and other people's permissions
CHGRP: Modifying a file's user group
Chown: Changing the owner of a file
If you are unfamiliar with the above commands, you can check out the appropriate commands for Linux.
