    E-MapReduce:Switch from pay-as-you-go to subscription

    Last Updated:Mar 05, 2025

    After you create a pay-as-you-go E-MapReduce (EMR) cluster or a subscription cluster that contains pay-as-you-go node groups, you can switch the billing method of the pay-as-you-go cluster or node groups to subscription. The subscription billing method allows you to reserve resources in advance and provides more cost savings.

    Prerequisites

    Note

    Make sure that the balance in your account is sufficient to cover the related fees.

    • 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.

      • Your cluster is in the Running state.

    • The node groups whose billing method you want to switch meet the following requirements:

      • The node groups are in the Running state and contain nodes.

      • No auto scaling rule is associated with the node groups.

    5. In the Switch to Subscription dialog box, configure the following parameters:

      1. Node Group Type: By default, master and core node groups are selected. You can select other node groups based on your business requirements. You cannot switch the billing method of a task node group for which auto scaling rules are configured from pay-as-you-go to subscription.

      2. Subscription Duration: Select an option from the drop-down list based on your business requirements.
