How does user permission management work in Hive?

The user access management in Hive is achieved through roles and permissions. In Hive, there are several roles available, including:

  1. Superuser: Having all permissions, able to access all databases and tables, able to execute all operations.
  2. Admin has the ability to modify databases and tables, as well as manage permissions for other users.
  3. Regular users have access to specified databases and tables, and can perform specified operations.

Users can be assigned to different roles and can have different permissions set for each user or role. Permissions include access to databases and tables, as well as operations that can be performed (such as SELECT, INSERT, UPDATE, DELETE, etc.). Users can be granted different levels of permissions, such as read-only or read-write access.

By managing roles and permissions, effective access control and permission management for Hive databases and tables can be achieved. Administrators can adjust the permissions of users and roles as needed to ensure data security and compliance.
