This release of the Cloudera Management Console 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 Cloudera 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 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 Cloudera Runtime versions support CentOS 7 only. Cloudera will not publish any updates or fixes for CentOS-based images after June 2024.
As part of the upgrade process of FreeIPA, Data Lake, and Cloudera Data Hub clusters, 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.
Discontinuation of Medium Duty Data Lake
Starting with Cloudera Runtime 7.2.18, Medium Duty Data Lake is discontinued and is replaced by Enterprise Data Lake. In order for existing Data Lakes to be upgraded to Runtime 7.2.18, they must be using Enterprise or Light Duty Data Lake.
Enterprise Data Lakes are a redefined version of Medium Duty Data Lakes that still offer failure resilience, but utilize resources and allocate memory more efficiently than a Medium Duty Data Lake at the same cost. Enterprise Data Lakes can handle more intensive workloads than Medium Duty Data Lakes and when deployed in Multi-AZ mode, remain operational during an availability zone outage.
If you are using Medium Duty Data Lake and would like to upgrade to Cloudera Runtime 7.2.18, you will first need to upgrade to 7.2.17 first, and then resize your Data Lake to Enterprise Data Lake. For more information, see Upgrading from Medium Duty to Enterprise Data Lake.
Support for Amazon S3 Express One Zone buckets
Starting with Runtime 7.2.18, CDP supports using S3 Express One Zone buckets for data storage. If you have additional data buckets that you would like to use for Cloudera Data Hub cluster workloads and you do not need zone redundancy, you may use S3 Express buckets, for example for faster processing of temporary data. For more information, see Using S3 Express One Zone for data storage.
Rolling upgrade support for the Data Lake
With the release of Cloudera Runtime 7.2.18, rolling upgrades for certain Data Lakes are now available. Rolling upgrades for the Data Lake are limited to certain Cloudera Runtime versions and shapes of Data Lakes. For more information, see Rolling upgrades.
