Amazon EMR 2.x and 3.x AMI versions - Amazon EMRAWS 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.
