Logging In to the Ranger Web UI¶
Ranger provides a centralized permission management framework to implement fine-grained permission control on components such as HDFS, HBase, Hive, and Yarn. In addition, Ranger also provides a web UI for system administrators to perform operations.
Ranger User Type¶
Ranger users are classified into admin, user, and auditor. Different users have different permissions to view and operate the Ranger management interface.
Admin: A security administrator can view all page content, manage permission management plug-ins and access control policies, view audit information, and set user types.
Auditor: An audit administrator can view the permission management plug-ins and access control policies.
User: A common user who can be assigned with specific permissions by the system administrator.
