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

To view historical clusters, choose Clusters > Cluster History. Select a cluster and click its name to switch to the cluster details page. You can click Cluster Details to view the configurations, deployed nodes, and other basic information.

Table 1, Table 2, Table 3, Table 4, and Table 5 describe the information about cluster configurations and nodes, respectively

Table 1 Cluster configuration information

Parameter

Description

Cluster Name

Cluster name

This parameter is set when a cluster is created.

Cluster Status

Status of a cluster

Cluster Details

Cluster details include basic information, node information, and component information. You can click Cluster Details to hide information.

Table 2 Basic information

Parameter

Description

Cluster Version

MRS version

Currently, MRS 1.8.10, MRS 1.9.2 and MRS 2.1.0 are supported.

This parameter is set when a cluster is created.

Cluster Type

MRS provides three types of clusters:
  • Analysis cluster: is used for offline data analysis and provides Hadoop components.
  • Streaming cluster: is used for streaming tasks and provides stream processing components.
  • Hybrid cluster: is used for both offline data analysis and streaming processing and provides Hadoop components and streaming processing components.

This parameter is set when a cluster is created.

Cluster ID

Unique identifier of a cluster

This parameter is automatically assigned when a cluster is created.

Created

Time when MRS starts charging MRS clusters of the customer

Billing Mode

Billing mode of a cluster

Currently, Yearly/Monthly and Pay-per-use are supported.

Order ID

Order ID for purchasing the cluster. This parameter is displayed only when Billing Mode is set to Yearly/Monthly.

AZ

AZ of the region in the cluster.

This parameter is set when a cluster is created.

VPC

VPC information

This parameter is set when a cluster is created.

A VPC is a secure, isolated, and logical network environment.

Subnet

Subnet information

This parameter is set when a cluster is created.

A subnet provides dedicated network resources that are isolated from other networks, improving network security.

EIP

After binding an EIP to an MRS cluster, you can use the EIP to access the MRS Manager page of the cluster.

Key Pair

Key pair name

This parameter is set when a cluster is created.

This parameter is not displayed if you set Login Mode to Password.

Enterprise Project

Enterprise project to which a cluster belongs. Only on the Active Clusters page, you can click the name of an enterprise project to go to its Enterprise Project Management page.

Table 3 Node information

Parameter

Description

Master Node

Information about the Master node

Format: [ECS type-instance specification | node count]

Master Node Storage Space

Storage space and type of data disks of the Master node

Core Node

Information about a Core node

Format: [ECS type-instance specification | node count]

Analysis Core Node is displayed for an analysis cluster. Streaming Core Node is displayed for a streaming cluster. Both Analysis Core Node and Streaming Core Node are displayed for a hybrid cluster.

Core Node Storage Space

Storage space and type of data disks of the Core node

Analysis Core Node Storage Space is displayed for an analysis cluster. Streaming Core Node Storage Space is displayed for a streaming cluster. Both Analysis Core Node Storage Space and Streaming Core Node Storage Space are displayed for a hybrid cluster.

Task Node

Information about a Task node

Format: [ECS type-instance specification | node count]

Analysis Task Node is displayed for an analysis cluster. Streaming Task Node is displayed for a streaming cluster. Both Analysis Task Node and Streaming Task Node are displayed for a hybrid cluster.

Task Node Storage Space

Storage space and type of data disks of the Task node

Analysis Task Node Storage Space is displayed for an analysis cluster. Streaming Task Node Storage Space is displayed for a streaming cluster. Both Analysis Task Node Storage Space and Streaming Task Node Storage Space are displayed for a hybrid cluster.

Task Node Auto Scaling

Auto Scaling can automatically adjust computing resources based on customers' service requirements and preset policies. With auto scaling, the number of instances in MRS tasks can increase and decrease as the service load increases and decreases, ensuring smooth operation of services.
