Cluster List

Updated at: Apr 28, 2020 GMT+08:00

The cluster list contains all clusters in MRS. You can view clusters in various states. If a large number of clusters are involved, navigate through multiple pages to view all of the clusters.

MRS, as a platform managing and analyzing massive data, provides a PB-level data processing capability. Multiple clusters can be created. The cluster quantity is subject to the ECS quantity.

Clusters are listed in chronological order by default in the cluster list, with the most recent cluster displayed at the top.

  • Active Clusters: contain all clusters except the clusters in the Failed and Terminated states.
  • Cluster History: contains the tasks in the Failed and Terminated states. Only clusters terminated within the last six months are displayed. If you want to view clusters terminated six months ago, contact technical support engineers.
  • Failed Tasks: only contain the tasks in the Failed state. Task failures include:
    • Cluster creation failure
    • Cluster termination failure
    • Cluster scale-out failure
    • Cluster scale-in failure
Table 1 Parameters in the active cluster list




Cluster name, which is set when a cluster is created.

Cluster Version

Cluster version.


Number of nodes that can be deployed in a cluster. This parameter is set when a cluster is created.


Status and operation progress description of a cluster.

The cluster creation progress includes:
  • Verifying cluster parameters
  • Applying for cluster resources
  • Creating VMs
  • Initializing VMs
  • Installing MRS Manager
  • Deploying the cluster
  • Cluster installation failed
The cluster scale-out progress includes:
  • Preparing for scale-out
  • Creating VMs
  • Initializing VMs
  • Adding nodes to the cluster
  • Scale-out failed
The cluster scale-in progress includes:
  • Preparing for scale-in
  • Decommissioning instance
  • Deleting VMs
  • Deleting nodes from the cluster
  • Scale-in failed

The system will display causes of cluster installation, scale-out, and scale-in failures. For details, see Table 6.


Time when MRS starts charging MRS clusters.


Time when a cluster node billing stops and the cluster node begins to be terminated. This parameter is valid only for historical clusters displayed on the Cluster History page.

Billing Mode

Currently, the commercial version of MRS is charged based on ECSs in a cluster.

  • Yearly/Monthly: The duration ranges from one month to one year. You need to pay in full when purchasing a cluster.
  • Pay-per-use: Nodes are charged by actual duration of use, with a billing cycle of one hour.


Availability zone (AZ) in the region of an cluster, which is set when a cluster is created.

Enterprise Project

Enterprise project to which the cluster belongs.


  • Terminate: If you want to terminate a cluster after jobs are complete, click Terminate. The cluster status changes from Running to Terminating. After the cluster is terminated, the cluster status will change to Terminated and will be displayed in Cluster History. If the MRS cluster fails to be deployed, the cluster is automatically terminated. No fee will be charged accordingly.
This parameter is displayed in Active Clusters only.

If a cluster is terminated before data processing and analysis are completed, data loss may occur. Therefore, exercise caution when terminating a cluster.

Table 2 Button description



In the drop-down list, select a status to filter clusters:

  • Active Clusters
    • All: displays all existing clusters.
    • Starting: displays existing clusters in the Starting state.
    • Running: displays existing clusters in the Running state.
    • Scaling out: displays existing clusters in the Scaling out state.
    • Scaling in: displays existing clusters in the Scaling in state.
    • Abnormal: displays existing clusters in the Abnormal state.
    • Terminating: displays existing clusters in the Terminating state.
    • Frozen: displays existing clusters in the Frozen state.

Click to open the page for managing failed tasks.

Num: displays the failed tasks in the Failed state.

Enter a cluster name in the search bar and click to search for a cluster.
