Cluster Type

There are 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. (MRS 1.8.5 or later supports hybrid clusters.)

Click Manage Agency to bind or modify an agency for the cluster.

An agency allows ECS or BMS to manage MRS resources. You can configure an agency of the ECS type to automatically obtain the AK/SK to access OBS. For details, see Accessing OBS Using an ECS Agency.

The MRS_ECS_DEFAULT_AGENCY agency has the OBS OperateAccess permission of OBS and the CES FullAccess (for users who have enabled fine-grained policies), CES Administrator, and KMS Administrator permissions in the region where the cluster is located.


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

Key Pair

Name of a key pair. Set this parameter when creating a cluster.

If the login mode is set to password during cluster creation, this parameter is not displayed.

Kerberos Authentication

Whether to enable Kerberos authentication when logging in to MRS Manager.
