How Do I Select an MRS Version?

MRS Cluster Versions

There are two MRS cluster versions: normal and LTS. The components and features of clusters of different versions are slightly different. You can select a version based on service requirements.

• Normal
  • Functions

    This normal version provides basic cluster operations, such as configuration, management, and O&M. For details, see MapReduce Service User Guide.

  • Components

    In addition to common components, clusters of the normal version also support components such as Presto, Impala, Kudu, and Sqoop. You can select components based on cluster versions. For details about components of clusters of different versions, see List of MRS Component Versions and MapReduce Service Component Operation Guide.

• LTS (long term support)
  • Functions

    In addition to basic cluster operations, clusters of the LTS version support version upgrade. To use this function, contact technical support.

  • Components

    In addition to common components, clusters of the LTS version also support HetuEngine. You can select components based on cluster versions. For details about components of clusters of different versions, see List of MRS Component Versions and MapReduce Service Component Operation Guide.

Version Selection Suggestions

• Clusters of the LTS version support version upgrade. To make your clusters upgradable, choose the LTS version.
• Clusters of the LTS version can be deployed in different AZs to implement cross-AZ DR. To make your clusters more secure and have higher DR capabilities, choose the LTS version.
• Clusters of the LTS version support HetuEngine. To use HetuEngine, choose the LTS version.
  

  After purchase, the LTS version cannot be changed to the normal version. Choose an appropriate version based on your business needs.

Billing Differences Between Versions

The normal and LTS versions have different functions and therefore they are billed differently. For details, see Billing. You can also use the price calculator to quickly calculate the reference price of an MRS cluster by selecting the cluster version and node specifications that you need.
