Configure Amazon EMR scale-down behavior

Note

The terminate at instance hour scale-down behavior option is no longer supported for Amazon EMR release 5.10.0 and higher. The following scale-down behavior options only appear in the Amazon EMR console for releases 5.1.0 through 5.9.1.

You can use the Amazon Web Services Management Console, the Amazon CLI, or the Amazon EMR API to configure scale-down behavior when you create a cluster.

Console
To configure scale-down behavior with the console

  1. Sign in to the Amazon Web Services Management Console, and open the Amazon EMR console at https://console.amazonaws.cn/emr.

  2. Under EMR on EC2 in the left navigation pane, choose Clusters, and then choose Create cluster.

  3. In the Cluster scaling and provisioning option section, choose Use custom automatic scaling . Under Custom automatic scaling policies, choose the plus action button to add Scale in policies. We recommend that you add both Scale in and Scale out policies. Adding in only one set of policies means Amazon EMR will only perform one-way scaling, and you have to manually perform the other actions.

  4. Choose any other options that apply to your cluster.

  5. To launch your cluster, choose Create cluster.

Amazon CLI
To configure scale-down behavior with the Amazon CLI

  • Use the --scale-down-behavior option to specify either TERMINATE_AT_INSTANCE_HOUR or TERMINATE_AT_TASK_COMPLETION.
