# 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](https://console.amazonaws.cn/emr).

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

1. 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.

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

1. 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`.
