Feature Introduction
Elastic MapReduce (EMR) clusters support the renewal feature, which ensures that monthly subscribed clusters do not become unavailable (isolated) due to payment issues. This document describes how to manually renew, enable auto-renewal, and cancel auto-renewal for monthly subscribed cluster nodes through the EMR console. After auto-renewal is enabled, the system will automatically renew resources before they expire. No manual action is required, and you do not have to worry about resources and data being deleted due to untimely renewal.
If the auto-renewal feature is not enabled, you can manually renew through the EMR console. Manual renewal supports a minimum renewal period of 1 month.
Renewal Rules
1. The renewal feature only supports monthly subscribed nodes. Pay-as-you-go nodes do not require renewal operations. Ensure your account balance is sufficient to guarantee normal renewals.
2. The monthly subscribed nodes to be renewed must be in normal operation status.
3. After you enable auto-renewal, resources will be renewed automatically every month on the expiration day. You need to ensure that your account balance is sufficient to prepay the fees for at least 1 month.
4. If there are available vouchers at the time of renewal, the system will automatically use them. For details, refer to the Voucher documentation. 5. If you manually renew before the deduction time, the system will automatically renew based on the latest expiration time.
Manual Renewal
1. Log in to the EMR console, and click the corresponding Cluster ID/Name in the cluster list to go to the cluster details page. 2. On the cluster details page, select Cluster Resources > Resources, select the corresponding resources, and click Renew or Pending Renewal to filter out the resources that need renewal to proceed with the renewal operation.
3. The default renewal duration is 1 month, which can be adjusted as needed.
Auto-renewal
Setting Auto-renewal in the EMR Console
When purchasing clusters and scaling out nodes in the EMR console, you can enable auto-renewal for monthly subscribed resources. If auto-renewal was not enabled for monthly subscribed resources during cluster purchase or node scale-out, you can follow these steps to set up auto-renewal later:
1. Log in to the EMR console, and click the corresponding Cluster ID/Name in the cluster list to go to the cluster details page. 2. On the cluster details page, select Cluster Resources to enter the Resources page. You can select nodes individually or in batches for settings.
When setting auto-renewal for a single node, an additional Set renewal option will appear in the More drop-down list of the operation column of the resource list.
When setting auto-renewal for nodes in batches, you can select Set renewal from the More drop-down list at the top.
Node auto-renewal: Select Enable.
3. To disable auto-renewal, follow the same operations as above.
Setting Auto-renewal for EMR Resources in the Billing Center
1. Log in to the EMR console, and click the corresponding Cluster ID/Name in the cluster list to go to the cluster details page. 2. On the cluster details page, select Cluster Resources to enter the Resources page, copy the corresponding resource ID, and go to Billing Center to set up auto-renewal. 3. In the Renewal Management > Manual Renewal section of the Billing Center console, find the resource that needs auto-renewal and set it to Auto-renewal.
4. After refreshing the EMR Console, you will see the word "Renew" next to the corresponding resource ID in Resources, indicating that auto-renewal has been enabled.
