EMR offers one billing mode for clusters:

• Pay-as-you-go: All nodes in a cluster are charged on a pay-as-you-go basis. This is suitable for clusters that exist for a short time or periodically.

Note：

Select the shutdown mode with caution when shutting down a pay-as-you-go EMR cluster node in the CVM console, because EMR nodes do not support the "no charges when shut down" mode.

For more information on node types, see Cluster Types.

When you purchase an EMR cluster, the price will be listed as an hourly fee. However, you will be billed by the actual seconds of usage and the charge will be rounded to two decimal places. Billing starts from the second the cluster is created and stops the second the cluster is terminated.

When you purchase a pay-as-you-go cluster, the fees for 2-hour usage under the current configuration will be frozen in your account balance as a deposit. You will then be billed by the hour (Beijing time) for your usage over the past hour. When you change the node configurations, the frozen amount will be unfrozen and a new 2-hour deposit will be frozen based on the unit price of the new configuration. Your deposit will be released back to your account when the cluster is terminated.

EMR provides elastic computing cluster capabilities, so that you can select and combine multiple EMR specifications in a customized manner. EMR fees are charged based on all nodes in each cluster. You can view node specification prices in Pricing | Elastic MapReduce to estimate resource fees.

Note：

• Published prices are subject to change.
• For the prices of disks, see CBS Price Overview.
• The following prices are for configuration fees of CPU and memory, excluding fees of images, system cloud disks, local data disks, data cloud disks, and bandwidth.

Other items that may incur costs include network traffic, metadata storage, and COS.

• Network traffic
  Public network access is enabled for the Master.1 node in a cluster by default so that you can access the WebUI pages of various Hadoop components from outside the cluster. Traffic fees are incurred for data interactions when you visit these pages, which is very little in most cases. Therefore, the bill-by-traffic mode is used by default, which costs less than the bill-by-bandwidth mode.
• Metadata storage
  The metadata storage such as Hive on EMR (v2.x and earlier) uses TencentDB, the fee of which is included in the total cost on the purchase page.
• COS
  When you separate computing and storage for a cluster via COS, data storage and request fees (see Pricing | Cloud Object Storage) will be incurred when the cluster pulls data from COS for computing. In addition, new data may be generated for the storage or backup of computing results in COS.
