April 2024

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

Cloudera 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 Cloudera Data Hub clusters. For more information about the new Runtime version, see Cloudera Runtime. If you need to upgrade your existing Cloudera environment, your upgrade path may be complex. To determine your upgrade path, refer to Upgrading to Cloudera 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 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 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 Cloudera 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 Cloudera Operational Database Data Hub clusters

With the release of Runtime 7.2.18, rolling upgrades for certain Cloudera Operational Database Data Hub clusters are now available. For more information, see Rolling upgrades.

Disk vertical scaling in Azure (Preview)

Disk vertical scaling (that is, disk type change and resizing) is now supported by Cloudera for Data Lakes and Cloudera Data Hub clusters running in Azure. Previously, only AWS support was available for this feature in Cloudera. For more information, see Disk Vertical Scaling - Disk Type Change and Resizing in AWS and Azure.
