Upgrading Amazon Kubernetes Service (EKS)

Amazon Elastic Kubernetes Service (EKS) cluster requires regular updates to the Kubernetes versions. Using the latest EKS version supported by Cloudera avoids compatibility issues between Cloudera Data Warehouse (CDW) and AWS resources.

CDW automatically provisions the latest supported EKS version when you activate an environment in CDW. EKS 1.29 is provisioned automatically when you activate your environment from CDW using release 1.9.1-b233 (released July 26, 2024) and later.

To upgrade to the latest EKS, you must deactivate and reactivate your CDW environment. To restore the state of your CDW cluster after reactivation, Cloudera recommends using the backup-restore functionality. For more information, see Backing up and restoring CDW.
