E-MapReduce:Renewal policy

Last Updated:Jan 29, 2024

Before a subscription cluster is automatically released, you can manually renew the cluster or enable auto-renewal for the cluster. After auto-renewal is enabled, the system renews your resources before the resources expire. This way, you do not need to manually renew resources, and your resources and data are not deleted due to resource expirations. This topic describes how to manually renew an E-MapReduce (EMR) cluster and enable and disable auto-renewal for an EMR cluster.

Background information

The renewal feature is applicable only to subscription clusters. Pay-as-you-go clusters do not need to be renewed. However, you must make sure that your account balance is sufficient to cover the fees.

The renewal items of an EMR cluster include the EMR service and ECS instances. EMR supports manual renewal and auto-renewal.

Prerequisites

The subscription cluster that you want to renew is in a normal state.

Precautions

  • If your cluster expires on the next day, you can only manually renew the cluster. Auto-renewal is not supported.

  • You can use coupons for auto-renewal.

  • After you enable auto-renewal, you must keep your account balance sufficient for auto-renewals.

Manually renew a cluster

  1. Go to the Renewal Management page.

    1. Log on to the EMR console. In the left-side navigation pane, click EMR on ECS.

    2. In the top navigation bar, select the region in which your cluster resides and select a resource group based on your business requirements.

    3. Find the desired cluster, move the pointer over the more icon in the Actions column, and then select Renew.

  2. On the Renewal Management page, configure renewal policies for the ECS instances and the EMR service.

    The following renewal methods are supported:

    • Quick renewal (recommended)

      If you want to configure a unified renewal policy for all ECS instances and the EMR instance in the cluster, you can use this method. Select a renewal period from the Renewal Setting drop-down list.Quick renewal

    • Custom renewal

      Important

      We recommend that you configure a unified renewal policy for all instances to prevent specific nodes from being released due to inconsistent expiration time.

      If you want to configure different renewal policies for the ECS instances and the EMR instance in the cluster, click Custom Renewal in the upper-right corner and separately select a renewal period for each ECS instance and the EMR instance from the Renewal Setting drop-down list. The following table describes the parameters on the custom renewal page.Renewal page

      Parameter

      Description

      Instance ID

      The cluster or instance ID. The Instance ID column in the EMR Instance section displays the ID of the EMR cluster. The Instance ID column in the ECS Instances section displays the IDs of the ECS instances.

      Cluster

      The name of the cluster.

      Node Group

      The name of the node group to which the ECS instance belongs.

      Expiration Time

      The time when the EMR instance or ECS instance expires.

      Renewal Setting

      Select a renewal period from the drop-down list.

  3. Read the terms of service, select the E-MapReduce Terms of Service check box, and then click Submit Order.

    Important

    If an unpaid order exists in the cluster list, you are not allowed to scale out or renew a cluster.

    After you click Submit Order, a message that indicates an order is created appears. Click Pay for Order. The Purchase page appears. This page displays the total amount that you need to pay and the details of each order.

  4. Complete the payment.

    After you complete the payment, the expiration time of the cluster on the Basic Information tab is updated based on the renewal period. In the ECS console, the expiration time of the ECS instances is updated after a delay of approximately 3 to 5 minutes.

Enable auto-renewal for a cluster

  1. Log on to the EMR console. In the left-side navigation pane, click EMR on ECS.

  2. Find the desired cluster, move the pointer over the more icon in the Actions column, and then select Auto-renewal.

  3. On the Auto-renewal page, configure auto-renewal policies for the ECS instances and the EMR instance.

    The following renewal methods are supported:

    • Quick auto-renewal (recommended)

      If you want to configure a unified auto-renewal policy for all the ECS instances and the EMR instance in the cluster, select a renewal period from the Configure Auto Renewal Rule drop-down list.

    • Custom auto-renewal

      Important

      We recommend that you configure a unified renewal policy for all instances to prevent specific nodes from being released due to inconsistent expiration time.

      If you want to configure different auto-renewal policies for the ECS instances and the EMR instance in the cluster, click Custom Auto-renewal Rule in the upper-right corner of the Auto-renewal page. Then, separately select an auto-renewal period for each ECS instance in the ECS Instances section and for the EMR instance in the EMR Instance section.

  4. Click OK.

    After auto-renewal is enabled, the resources are automatically renewed before they expire, and no manual operation is required. You need to only make sure that your account balance is sufficient.

Disable auto-renewal for a cluster

If you enable auto-renewal for your cluster, the system deducts fees from your account balance nine days before the cluster expires. If you no longer require auto-renewal for the cluster after the current billing cycle, you can disable auto-renewal for the cluster before the system deducts the fees for the next billing cycle.

  1. Log on to the EMR console. In the left-side navigation pane, click EMR on ECS.

  2. Find the desired cluster, move the pointer over the more icon in the Actions column, and then select Auto-renewal.

  3. On the Auto-renewal page, disable auto-renewal for the ECS instances and the EMR instance.

    • If you want to disable auto-renewal for all the ECS instances and the EMR instance in the cluster, select Auto-renewal Disabled from the Configure Auto Renewal Rule drop-down list.

    • If you want to disable auto-renewal for specific ECS instances or the EMR instance in the cluster, click Custom Auto-renewal Rule in the upper-right corner of the Auto-renewal page. Then, select Auto-renewal Disabled from the Configure Auto Renewal Rule drop-down list for each desired ECS instance in the ECS Instances section or for the EMR instance in the EMR Instance section.

  4. Click OK.
