April, 2024

This release of the Data Hub service introduces the following changes:

Runtime 7.2.18

Cloudera Runtime 7.2.18 is now available and can be used for registering an environment with a 7.2.18 Data Lake and creating Data Hub clusters. For more information about the new Runtime version, see Cloudera Runtime. If you need to upgrade your existing CDP environment, your upgrade path may be complex. To determine your upgrade path, refer to Upgrading to Runtime 7.2.18 documentation.

RHEL replaces CentOS as default OS

As of June 30, 2024, CentOS reaches End of Life (EOL), and consequently, Cloudera Runtime 7.2.18 supports RHEL 8 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.

As part of FreeIPA, Data Lake, and Data Hub upgrade, you have the option to upgrade the operating system (OS) on the virtual machines (VMs) from CentOS 7 to Red Hat Enterprise Linux 8 (RHEL 8). For more information, see Upgrading from CentOS to RHEL.

Rolling upgrade support for Data Hubs

With the release of Runtime 7.2.18, rolling upgrades for certain Data Hubs are now available. For more information, see Rolling upgrades.
