# Configure provisioning timeouts for cluster launch in Amazon EMR
Provisioning timeout for launch

You can define a timeout period to provision Spot Instances for each fleet in your cluster. If Amazon EMR can't provision Spot capacity, you can choose either to terminate the cluster or to provision On-Demand capacity instead. If the timeout period ends during the cluster resizing process, Amazon EMR cancels unprovisioned Spot requests. Unprovisioned Spot instances aren't transferred to On-Demand capacity.

Perform the following steps to customize a provisioning timeout period for cluster launch with the Amazon EMR console.

------
#### [ Console ]

**To configure the provisioning timeout when you create a cluster with the console**

1. Sign in to the AWS Management Console, and open the Amazon EMR console at [https://console.aws.amazon.com/emr](https://console.aws.amazon.com/emr).

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

1. On the **Create Cluster** page, navigate to **Cluster configuration** and select **Instance Fleets**.

1. Under **Cluster scaling and provisioning option**, specify the Spot size for your core and task fleets.

1. Under **Spot timeout configuration**, select either **Terminate cluster after Spot timeout** or **Switch to On-Demand after Spot timeout**. Then, specify the timeout period for provisioning Spot Instances. The default value is 1 hour.

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

1. To launch your cluster with the configured timeout, choose **Create cluster**.

**To specify a provisioning timeout with the `create-cluster` command**

```
