ApsaraDB for HBase:Manage users

Last Updated:Mar 30, 2026

Use LindormTable's cluster management system to create users, manage their passwords, and control what data they can access.

Prerequisites

Before you begin, ensure that you have:

Create a user

  1. In the left-side navigation pane, choose Data Manager > User Manager.

  2. Click + Add user on the right side of the page.

  3. In the Add user dialog box, enter a Username and Password.

  4. Click OK.

Note

After the user is created, the password is no longer visible in the system. If you forget it, change the password. New users have no permissions by default — grant permissions after creating the account.

Delete a user

  1. Find the user you want to delete and click Delete in the Operation column.

  2. Click OK.

Change a password

  1. In the Operation column for the user, click Change password.

  2. In the Change password dialog box, enter a New password.

  3. Click OK.

Permission management

Grant permissions to or revoke permissions from a user directly in the cluster management system.

Permission levels

Three permission levels control access to Lindorm resources, from broadest to narrowest: Global, Database (Namespace), and Table. A higher level includes all permissions of the levels below it.

For example, if User 1 is granted the global read and write permissions, User 1 has the read and write permissions on wide tables in all databases in a Lindorm cluster. If User 2 is granted the read and write permissions on Database 1, User 2 has the read and write permissions on all tables in Database 1, including newly created tables in Database 1.

Permissions

The following permissions control what operations a user can perform:

Permission Operations Syntax
WRITE Write data to tables PUT, BATCH, DELETE, INCREMENT, APPEND, and CHECKANDMUTATE
READ Read data from tables; read table descriptor and namespace information GET, SCAN, and EXIST; GETTABLEDESCRIPTOR, LISTTABLES, and LISTNAMESPACEDESCRIPTORS
ADMIN Data Definition Language (DDL) operations (excluding deleting tables or table data); namespace DDL operations CREATETABLE, ENABLETABLE, and DISABLETABLE; CREATENAMESPACE
TRASH Operations that prevent accidental deletion of tables or table data TRUNCATETABLE and DELETETABLE
SYSTEM O&M operations; data migration and synchronization using LTS COMPACT and FLUSH

Grant and revoke permissions

  1. In the Operation column for the user, click More. image.png

  2. From the drop-down list, select the operation:

    • Grant permissions: grant Global, namespace, or table permission to the user.

    • Revoke permissions: revoke Global, namespace, or table permission from the user.

  3. In the dialog box, select or deselect the permissions and the related scope information.

  4. Click OK.
