Upgrading to Runtime 7.2.18

Cloudera Data Platform (CDP) Public Cloud Runtime 7.2.18 introduces significant new features and improvements. As a result, if you are planning to upgrade the Runtime version in your existing Data Lake or Data Hub clusters to 7.2.18, you might be required to perform this in multiple steps.

Some of the important 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, Runtime 7.2.18 supports RHEL 8-based images only. New deployments of Data Lakes and Data Hubs with Runtime 7.2.18 and upgrades to 7.2.18 are only possible with RHEL 8. Data Lake and Data Hub clusters running Runtime 7.2.17 support both CentOS 7 and RHEL 8. Earlier 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 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 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.

Use the following documentation to identify your Data Lake cluster’s version details and then based on that determine your upgrade path:
