Upgrading to Cloudera Runtime 7.2.18
Cloudera Runtime 7.2.18 introduces significant new features and improvements. As a result, if you are planning to upgrade the Cloudera Runtime version in your existing Data Lake or Cloudera Data Hub clusters to 7.2.18, you might be required to perform this in multiple steps.
Some of the important Cloudera Runtime 7.2.18 features include:
-
RHEL 8 images as CentOS reaches End of Life (EOL)
As of June 30, 2024, CentOS reaches End of Life (EOL), and consequently, Cloudera Runtime 7.2.18 supports RHEL 8-based images only. New deployments of Data Lakes and Cloudera Data Hub clusters with Cloudera Runtime 7.2.18 and upgrades to 7.2.18 are only possible with RHEL 8. Data Lake and Cloudera Data Hub clusters running Cloudera Runtime 7.2.17 support both CentOS 7 and RHEL 8. Earlier Cloudera Runtime versions support CentOS 7 only. Cloudera will not publish any updates or fixes for CentOS-based images after June 2024.
For Azure environments, Cloudera only provides RHEL 8 images via Azure Marketplace.

Discontinuation of Medium Duty Data Lake
Starting with Cloudera Runtime 7.2.18, Medium Duty Data Lake is discontinued as it does not support rolling upgrades and horizontal scaling, which have been introduced with the Enterprise Data Lake . While earlier Cloudera Runtime versions support Medium Duty Data Lake (7.2.17 supports Enterprise, Medium Duty, Light Duty, and older versions support Medium Duty and Light Duty), 7.2.18 only supports Enterprise and Light Duty Data Lakes.
