E-MapReduce:Renewal policy

Prerequisites

Before you begin, make sure that:

• The cluster is in the Running state

• Your account has no unpaid orders

Renewal rules

• Clusters eligible for manual renewal: Running and not yet expired, or expired but not yet released.

• If ECS instances in the cluster expire and are not renewed within 15 days, the instances and their data are deleted on the 15th day.

• The system starts deducting fees for auto-renewal three days before the service expires. Ensure that your account has a sufficient balance.

• The cluster is renewed for the duration you specify. For example, selecting three months extends the expiration date by three months.

Renew a cluster

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

2. In the top navigation bar, select a region and resource group.

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

4. On the Renewal Management page, configure renewal policies for the ECS instances and the EMR instance. Two renewal methods are supported:

   • Quick renewal (recommended) Select a renewal period from the Renewal Setting drop-down list. This applies a unified policy to all ECS instances and the EMR instance in the cluster.

   • Custom renewal

     Important

     Use a unified renewal policy for all instances to prevent nodes from being released due to inconsistent expiration times.

     Click Custom Renewal in the upper-right corner. Select a renewal period from the Renewal Setting drop-down list separately for each ECS instance and for the EMR instance.

     

     Parameter	Description
     Instance ID	The cluster or instance ID. In the EMR Instance section, this shows the EMR cluster ID. In the ECS Instances section, this shows the IDs of the ECS instances.
     Cluster	The name of the cluster.
     Node Name	The name of the node.
     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.

5. Read the terms of service and click Submit Order. After you click Submit Order, an order confirmation message appears. Click Pay for Order to open the Purchase page, which shows the total amount and order details.

   Important

   If an unpaid order exists in the cluster list, scale-out and renewal operations are not allowed.

6. Complete the payment. After payment, the expiration time on the Basic Information tab is updated within one hour. To view the updated time immediately, see Refresh the expiration time.

Prerequisites

Before you begin, make sure that:

• The cluster is in the Running state

• Auto-renewal is enabled at least two days before the cluster expires. The configuration takes effect the next day.

• Your account has sufficient balance, including cash, vouchers, and coupons, to cover the renewal fees

If a cluster expires the next day, manually renew it instead of enabling auto-renewal.

Auto-renewal rules

• The system deducts the renewal fees three days before the cluster expires.

• The cluster is renewed for the duration you specified when enabling auto-renewal.

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 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. Two auto-renewal methods are supported:

   • Quick auto-renewal (recommended) Select a renewal period from the Configure Auto Renewal Rule drop-down list. This applies a unified policy to all ECS instances and the EMR instance in the cluster.

   • Custom auto-renewal > Important: Use a unified renewal policy for all instances to prevent nodes from being released due to inconsistent expiration times. Click Custom Auto-renewal Rule in the upper-right corner. In the ECS Instances section, select an auto-renewal period for each ECS instance. In the Configure Auto Renewal Rule section, select an auto-renewal period for the EMR instance.

4. Click OK.
