Getting Started with Amazon AWS
AWS services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon AWS.

Amazon EMR

Amazon EMR helps you analyze and process vast amounts of data by distributing the computational work across a cluster of virtual servers running in the AWS Cloud. The cluster is managed using an open-source framework called Hadoop. Amazon EMR lets you focus on crunching or analyzing your data without having to worry about time-consuming setup, management, and tuning of Hadoop clusters or the compute capacity they rely on.

Please note the following Amazon AWS implementation particulars, which are potentially relevant to all services in the Beijing and Ningxia Regions.

  • To use services in the Beijing and Ningxia Regions, you need an account and credentials specific to the Beijing and Ningxia Regions. Accounts and credentials for other AWS Regions will not work for services operating in the Beijing and Ningxia Regions. Likewise, accounts and credentials for the Beijing and Ningxia Regions will not work for other AWS Regions.

  • There are two Availability Zones in the Beijing Region.

  • There are three Availability Zones in the Ningxia Region.

  • In AWS Identity and Access Management (IAM), you can grant or deny a service access to resources using the Principal policy element. Service principal values vary by Region.

  • The domain for both the Beijing and Ningxia Regions is www.amazonaws.cn.

  • The endpoints for services in the China (Beijing) Region and the China (Ningxia) Region are different from other global endpoints.

    • The endpoint domain for both the Beijing and Ningxia Regions is amazonaws.com.cn.

    • For an endpoint in the China (Beijing) Region, the Region value should be cn-north-1.

    • For an endpoint in the China (Ningxia) Region, the Region value should be cn-northwest-1.

    • For example, the endpoint for Elastic Load Balancing in the Beijing Region is elasticloadbalancing.cn-north-1.amazonaws.com.cn.

    Endpoint syntax varies from service to service. For more information, see China (Beijing), China (Ningxia), and the service-specific documentation.

  • In the China Regions, the Amazon Resource Name (ARN) syntax includes a cn.

    For example: arn:aws-cn:iam::123456789012:user/division_abc/subdivision_xyz/Bob.

  • The EC2-Classic platform is not supported.

  • AWS Marketplace is not supported.

  • The free usage tier is not available in the China Regions.

Note

The AWS documentation might show code examples for endpoints and ARNs that are not specific for the Beijing and Ningxia Regions. When using examples, verify you are using the correct endpoints and ARNs for your Region.

Feature Availability and Implementation Differences

The Amazon AWS implementation of Amazon EMR is unique in the following ways:

  • Amazon EMR does not support AMI version 2.4.11 and earlier in the Beijing and Ningxia regions. The China (Ningxia) region only supports Amazon EMR version 4.9.1 and later.

  • YARN Application history is not available on the cluster details page.

  • The following table indicates which instance are available to be used with Amazon EMR in the Beijing and Ningxia regions. Yes appears for regions where the instance type is available.

User Guides

Amazon AWS user guides are available in HTML and PDF, in both Chinese and English. API guides are available in HTML and PDF, in English only. Currently, the API guides are not available in the Beijing and Ningxia Regions. Links to API guides will take you to the global AWS site. Note that some features and functionality described in the guides may not be available in the current Amazon AWS release.

Command Line Interface (CLI)

To interact with Amazon Web Services from the command line, you can use the AWS Command Line Tools. For some services, a service-specific command line interface (CLI) is also available.
