Introduction

ApsaraDB for HBase Performance-enhanced Edition provides a new cluster management system. You can view the cluster space usage, servers, table properties, table sizes, and other information in this system. You can also manage namespaces, users, and ACLs in the cluster management system. The portal of the cluster management system is available in the ApsaraDB for HBase console. You can click the ClusterMananger hyperlink to log on to the system.

The cluster management system includes the following sections:

Homepage

On the homepage, you can view the following cluster information:

Cluster space usage

In this section, you can view the space usage of your cluster. Based on this information, you can decide whether to expand the disk of your cluster.

Group information

In this section, you can view all groups in your cluster, and manage these groups. For more information about groups, see Manage groups.

Server list

In this section, you can view all active RegionServers, and their statuses. For example, you can click a RegionServer name to view details about the RegionServer, including the region information. You can add RegionServers to different groups in order to isolate them. For more information about groups, see Manage groups.

Cluster health information

This section shows faulty RegionServers and inactive RegionServers. When ApsaraDB for HBase balances or splits regions, the regions will be temporarily inactive. However, if you find out that a region or RegionServer remains inactive for a long period of time, submit a ticket to report this problem or consult the ApsaraDB for HBase DingTalk group.

Namespace information

On the Namespaces page, you can view all namespaces in your cluster, and manage these namespaces. For more information about how to manage namespaces, see Manage groups.

Tables

On the tables page, you can view all tables in your cluster and their properties. You can click a table name to view detailed information about the table, and the region information.

Users

On the users page, you can view the users of your cluster, and their permissions. You can create users, change passwords, and delete users. For more information, see Manage users and ACLs.

Permissions

On the permissions page, you can grant permissions to a user or revoke permissions from a user. For more information, see Manage users and ACLs.

SQL queries

On the SQL queries page, you can run SELECT statements to query tables. For more information, see SQL queries.
