Introduction to Cluster List
After logging into the YI-MapReduce console, you can view the list of clusters under your account and their current status.
Cluster Status
The table below illustrates the statuses of a cluster.
Status | Description |
Starting | The cluster creation is in progress and can be tracked. |
Running | The cluster is successfully established and all its components are functioning properly. |
Abnormally Terminated | The cluster startup failed or was terminated due to an error. You can view the cause of termination at Reason for Failure. |
Releasing | This indicates that the cluster is in the process of unsubscription. |
Terminated | The cluster has expired for more than 15 days or has been unsubscribed. |
Frozen | For a cluster that has expired, resources are retained for 15 days, during which its status is marked as frozen. |
View Cluster Status
Once the cluster creation is complete, you can log in to the YI-MapReduce console to check the list and status of all clusters in your account.
Within My Cluster, you can see all clusters that you have created. The default view displays up to 10 cluster information entries. If you have many clusters, you can modify the maximum number of cluster entries displayed on the page at the bottom right, or you can navigate through different pages.
Description of the parameters in the cluster list:
Parameter | Parameter Description |
Cluster Name | The cluster name set by the user. |
Cluster Type | The cluster type selected by the user during creation. |
Payment Type | Annual or monthly by default. |
Status | Current status of the cluster. |
Creation Time | The time when the cluster was created. |
View Basic Cluster Information
After logging into the YI-MapReduce console, go to the cluster list page. Click on the cluster name needed to enter its basic information page.
The basic information parameters for the cluster mainly include details about the cluster, software, and network hardware.

In daily operations, users can use YI-MapReduce Manager to monitor the status and metric information of all components (including role instances) and hosts:
• Status information includes running status, health status, and role instance status statistics.
• Metric information includes the main monitoring metrics for each component.
Manage Component Monitoring
1. Go to the YI-MapReduce Manager page and select Cluster Service from the left menu.
2. Click on any cluster in the Cluster Service list to enter.
3. Choose the Cluster Status page to view the health status of instance groups.
Status | Description |
Alarm | Exceptions have occurred in the cluster instance service. |
Fault | The cluster instance service has encountered a failure. |
Normal | The cluster instance service is running. |
Not monitored | The cluster instance does not have Prometheus installed. The service is not being monitored. |
4. Click on the health status of any instance to go to the Role Instance page. It displays the role of each instance component, host IP, host name, host status, startup status, and health status, grouped by instance.
Manage Host Monitoring
1. Go to the YI-MapReduce Manager page and select Host from the left menu.
2. The host page shows various details such as Host IP, Host Name, Initialization Status, Host Status, Health Status, Host Label, Memory, CPU Model, Host Configuration, Operating System, Description, etc.
3. The Health Status column displays the health status of the host.
Status | Description |
Alarm | Exceptions have occurred in the cluster instance service. |
Fault | The cluster instance service has encountered a failure. |
Normal | The cluster instance service is running. |
Not monitored | The cluster instance does not have Prometheus installed. The service is not being monitored. |
4. Click on the Host IP to go to the Host Status information bar, which displays the host status, instance list, and alarm history.
5. Click on Alarm History to view the historical alarms associated with the specific host IP.
