Amazon EMR 2.x and 3.x AMI versions


AWS is updating the TLS configuration for all AWS API endpoints to a minimum version of TLS 1.2. Amazon EMR releases 3.10 and lower only support TLS 1.0/1.1 connections. After December 4, 2023, you won't be able to create clusters with Amazon EMR 3.10 and lower.

If you use Amazon EMR 3.10 or lower, we recommend that you immediately test and migrate your workloads to the latest Amazon EMR release. For more information, see the AWS Security Blog.

Amazon EMR 2.x and 3.x releases, called AMI versions, are made available for pre-existing solutions that require them for compatibility reasons. We do not recommend creating new clusters or new solutions with these release versions. They lack features of newer releases and include outdated application packages.

We recommend that you build solutions using the most recent Amazon EMR release version.

The scope of differences between the 2.x and 3.x series release versions and recent Amazon EMR release versions is significant. Those differences range from how you create and configure a cluster to the ports and directory structure of applications on the cluster.

This section attempts to cover the most significant differences for Amazon EMR, as well as specific application configuration and management differences. It is not comprehensive. If you create and use clusters in the 2.x or 3.x series, you may encounter differences not covered in this section.
