You can switch the billing method of a pay-as-you-go E-MapReduce (EMR) cluster to subscription. The subscription billing method allows you to reserve resources in advance and receive discounts. This topic describes how to switch the billing method of a cluster from pay-as-you-go to subscription.
Prerequisites
The cluster whose billing method you want to switch meets the following requirements:
The cluster belongs to your Alibaba Cloud account.
The cluster does not have an unpaid order for billing method switching.
If an unpaid order for billing method switching exists, you must cancel the unpaid order and place another order to switch the billing method.
The cluster is in a normal state.
Limits
You are not allowed to switch the billing method of a cluster from subscription to pay-as-you-go.
You are not allowed to switch the billing method of a node group for which auto scaling rules are configured from pay-as-you-go to subscription. If you want to switch the billing method of a node group for which auto scaling rules are configured from pay-as-you-go to subscription, delete the auto scaling rules first.
Procedure
If you switch the billing method from pay-as-you-go to subscription for a cluster, all resources in the cluster are billed based on the new billing method, and you can no longer switch the billing method back to pay-as-you-go from subscription.
Log on to the EMR console. In the left-side navigation pane, click EMR on ECS.
In the top navigation bar, select the region where your cluster resides and select a resource group based on your business requirements.
On the EMR on ECS page, find the cluster whose billing method you want to switch, move the pointer over the
icon in the Actions column, and then select Switch to Subscription. In the message that appears, click OK.
In the Switch to Subscription dialog box, select an option from the Subscription Duration drop-down list.
Read the terms of service, select E-MapReduce Terms of Service, and then click OK.
