E-MapReduce:Billing FAQ

Auto-renewal support

Yes, E-MapReduce supports auto-renewal for both the EMR service and its ECS instances. For details, see Renewal.

View expiration time

To view the expiration time for an EMR cluster, go to the E-MapReduce console, click the name of your target cluster, and view the details in the Cluster Information section on the Basic Information tab.

To view the expiration time for the ECS instances, go to the E-MapReduce console. In the Actions column for your target cluster, click > Renew, then click Custom Renewal to see the expiration time for each ECS instance.

Expiration notifications

Yes. When an EMR cluster or any of its ECS instances are about to expire, you can find expiration reminders in the E-MapReduce console under Events > Expense Events in the left-side navigation pane. You can also subscribe to EMR expense events in CloudMonitor to receive notifications. The system sends expiration reminders three days in advance.

Billing for expired clusters with unexpired instances

If an EMR cluster expires but its ECS instances have not, the cluster becomes unavailable, but billing continues for the running nodes.

This situation typically occurs when the expiration times for the EMR instance and its ECS instances are not aligned. After you scale out a cluster, you should immediately synchronize the expiration times. To do this, find your cluster in the E-MapReduce console, click > Renew in the Actions column, then click Custom Renewal. For detailed steps, see Renewal.

If your EMR instance has already expired, renew it as soon as possible. In the E-MapReduce console, find your cluster, click > Renew in the Actions column, then click Custom Renewal to renew only the EMR instance.

Additionally, if auto-renewal is already enabled for the ECS instances in your cluster, you can also enable it for the EMR instance. In the Actions column for your cluster, click > Auto-renewal, then click Custom Auto-renewal Rule to set up an auto-renewal rule for the EMR instance.

Change billing method

You can only change the billing method from pay-as-you-go to subscription. You cannot change from subscription to pay-as-you-go. For instructions, see Switch from pay-as-you-go to subscription.

Charges for unpaid orders

• Pay-as-you-go clusters: After you submit a creation request, billing for the ECS instances starts as soon as they are created. EMR service fees apply only after the cluster is successfully created.

• Subscription clusters: No charges apply to an unpaid order.

E-MapReduce billing

E-MapReduce supports both subscription and pay-as-you-go billing methods. For EMR on ECS, the total cost for a cluster consists of E-MapReduce service fees and ECS instance fees. The EMR service fees depend on the specifications of the selected ECS instances. For more information, see Billing.

Configure auto-renewal

Auto-renewal is available only for subscription clusters. For details, see Renewal.

Manual renewal for four years

First, renew the cluster for two years. Once that renewal is successful, renew it for another two years. For detailed instructions on manual renewal, see Manual renewal.
