    ApsaraDB for HBase:Group management

    Last Updated:Aug 21, 2026

    The group feature in ApsaraDB for HBase Performance-enhanced Edition (Lindorm) provides multi-tenant data isolation. You can assign RegionServers to different groups and store different tables in each group to isolate resources. This topic describes how to manage groups.

    Background information

    When multiple users or services use the same ApsaraDB for HBase Performance-enhanced Edition (Lindorm) cluster, resource contention can occur. Important online read and write operations might be affected by offline batch read and write operations. ApsaraDB for HBase Performance-enhanced Edition (Lindorm) provides the group feature to address this issue. As shown in the following figure, you can create Group1 and assign RegionServer1 and RegionServer2 to it. Then, create Group2 and assign RegionServer3 and RegionServer4 to it. You can also move Table1 and Table2 to Group1. All regions of Table1 and Table2 are assigned only to RegionServer1 and RegionServer2 in Group1. Similarly, all regions of Table3 and Table4 are assigned only to RegionServer3 and RegionServer4 in Group2. As a result, requests sent to Table1 and Table2 are handled only by RegionServer1 and RegionServer2, while requests sent to Table3 and Table4 are handled only by RegionServer3 and RegionServer4. This isolates the resources.分组管理架构图

    Prerequisites

    You must be logged on to the cluster management system of the destination cluster. For more information, see Log on to the cluster management system.

    View group information

    1. In the left-side navigation pane of the cluster management system, choose Cluster Management > Server Manager.

    2. The bottom of the page displays information about all groups in the current cluster.

      Note

      If you have not created any groups, the system automatically creates a group named default. All RegionServers and tables belong to this group.

    Create a group

    1. In the left-side navigation pane of the cluster management system, choose Cluster Management > Server Manager.

    2. In the upper-right corner of the page, click + Add.image.png

    3. In the New group dialog box, enter a Group Name.添加分组名

    4. Click Determine.

      Note

      After you create a group, it contains no servers or tables. You must move RegionServers and tables into the new group.

    Delete a group

    Important

    You can delete a group only after moving all of its RegionServers and tables out of it.

    1. In the left-side navigation pane of the cluster management system, choose Cluster Management > Server Manager.

    2. Find the target group and in the Operation column, choose More > Delete.image.png

    3. In the confirmation dialog box, click Determine.

    Move a RegionServer

    Important

    • By default, all RegionServers belong to the default group. To use a RegionServer in a different group, you must move it there.

    • Moving a table to a group with no RegionServers makes its regions inaccessible because no servers are available to bring them online.

    • For high availability, assign at least two RegionServers to each group. If one RegionServer fails, its regions can fail over to the other RegionServer in the same group. If a group has only one RegionServer and it fails, all tables in that group become unavailable.

    • When you move a RegionServer, the system immediately redistributes its active regions to other RegionServers within the original group.

    1. In the left-side navigation pane of the cluster management system, choose Cluster Management > Server Manager.

    2. Find the target RegionServer and in the Operation column, choose More > Move group.

    3. In the Move group dialog box, select a Target group.

    4. Click Determine.

    Move a table

    Warning

    Do not move a table to a group that has no servers. Otherwise, the table becomes inaccessible.

    1. On the Overview page, find the target table and click Move group in the Operation column.image.png

    2. In the Move group dialog box, select a Target group.

    3. Click Determine.
