E-MapReduce:Renewal policy

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.

• If you enable auto-renewal for your cluster, the system deducts fees from your account balance three days before the cluster expires. Make sure that you have sufficient balance within your account.

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 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.

   • 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.

     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 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.Configure Auto Renewal Rule

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 three 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 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.
