Clusters are listed in chronological order by default, with the latest cluster displayed at the top. Table 1 and Table 2 provides parameters and icons in the cluster list.

**Table 1** Cluster management parameters
Parameter	Description
Cluster Name	Name of a cluster. Set this parameter when creating a cluster.
Cluster Status	Cluster status, including Creating, In service, Sub-health, and Creation failed, and Frozen.
Task Status	Task status of a cluster For details, see Table 4.
Database Engine	HBase and ClickHouse
Cluster Version	Cluster kernel version
Enterprise Project	You can group related cloud resources (for example, resources used for the same purpose) and manage them by enterprise project. NOTE: You can delete a user that was authorized to manage an enterprise project if the enterprise's business has changed and the user should not have the permissions to manage the enterprise project. You can delete a user or multiple users. After a user that was authorized to manage an enterprise project is deleted, the user cannot manage the enterprise project. If the user needs to manage the enterprise project, authorize the user to manage the enterprise project again.
Created	Time when a cluster is created
Billing Mode	Cluster billing mode.
ZK Link (Intranet)	ZooKeeper address
Operation	Click Monitor to access the CloudTable service monitoring page. Node Scale Out: Increase compute units in the cluster. For details, see Scaling Out HBase Cluster Nodes. More Restart: Click Restart to restart a cluster. For details, see Restarting a Cluster. Delete: You can click Delete to delete a cluster. For details, see Deleting a Cluster. Enable Thrift Server: Click Enable Thrift Server to enable Thrift Server for the cluster. Disable Thrift Server: Click Disable Thrift Server to disable Thrift Server for the cluster.

Cluster Status

**Table 3** Cluster status description
Status	Description
Creating	Indicates that a cluster is being created.
In service	If a cluster is successfully created and can provide services, the cluster status is In service.
Sub-health	If the cluster status cannot be monitored within the specified time, the cluster status changes to Sub-health. Manual intervention is required to recover a cluster that is in Sub-health status. For example, you can restart the cluster to recover the cluster.
Creation failed	Indicates that a cluster fails to be created.
Frozen	If the balance is insufficient for renewing a cluster, the cluster status is Frozen. To unfreeze the cluster, you need to recharge your account to ensure that the account balance is not 0.. NOTE: A frozen cluster is unavailable and its all ECSs are shut down. After being unfrozen, the cluster recovers to the In service state. If you do not renew the cluster before the freeze period ends, the cluster will be deleted.
