You can now create Amazon EMR clusters with custom Amazon Machine Images (AMI) running Amazon Linux. This enables you to preload additional software on your AMI and use AMIs that you customize and control. You can also encrypt the Amazon EBS root volume of your AMIs with AWS Key Management Service (KMS) keys. Additionally, you can now adjust the Amazon EBS root volume size for instances in your Amazon EMR cluster. Previously, this was fixed at 10 GiB.
You can create Amazon EMR clusters with custom Amazon Linux AMIs from the Amazon EMR console, AWS Command Line Interface (CLI), or the AWS SDK with the Amazon EMR API. Custom AMIs are supported on Amazon EMR release 5.7.0 or later.
You can launch Amazon EMR clusters with custom AMIs in all supported regions for Amazon EMR.
