    Refund method

    Subscription

    Subscription clusters are paid based on the subscription period when the clusters are created. After an Elastic Compute Service (ECS) instance on which your EMR cluster is deployed is released, the system refunds you the fees for unused resources.

    Note

    Releasing an ECS instance is equivalent to downgrading the specifications of an EMR cluster. Each time an ECS instance is released, a downgrade order is generated. After all the ECS instances of an EMR cluster are released, you cannot continue to downgrade the specifications of the cluster.

    During the downgrade, the refundable amount is calculated based on the following formula:

    • Refundable amount for the downgrade of resource specifications = Online refundable amount × Price difference ratio between new and original orders. If multiple orders are generated, the sum of the refunds for the orders is calculated.

    • Online refundable amount = Paid amount - Fees for consumed resources

    For information about refund policies, see Rules for unsubscribing from resources.

    Important

    EMR does not support the refund of fees incurred by the renewal of a subscription EMR cluster.

    1. Release the ECS instances of the EMR cluster that you no longer require. For more information, see Release an instance.

    2. After the ECS instances are released, go to the Orders page of the Expenses and Costs console to view the refunds.

    Pay-as-you-go

    You are billed for pay-as-you-go clusters only after you use the clusters. Refunding is not supported for pay-as-you go resources.

    Note

    If you no longer require a pay-as-you-go EMR cluster, you can release the cluster. Before you release the EMR cluster, make sure that data in the cluster is backed up or migrated and your business is not affected. After you release the cluster, you are no longer charged for the cluster.
