Amazon EMR 2.x and 3.x AMI versions

Note

This topic replaces the Amazon EMR Developer Guide, which has been retired.

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 They lack features of newer releases and include outdated application packages.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.
