Ubuntu 24.04 support for Cloudera Manager 7.13.2

Starting with the Cloudera Manager 7.13.2.0 release, Cloudera Manager provides support for Ubuntu 24.04. This update ensures seamless compatibility with Ubuntu version 24.04, offering greater flexibility and platform options.

Ubuntu 24.04 supports only the Python 3.11 version in the Cloudera Manager 7.13.2 release.

Managing Service Restarts on Ubuntu 24.04:

Overriding needrestart Automatic Restart Behaviour

Ubuntu 24.04 (Noble Numbat) introduced a significant change to the default behavior of the needrestart utility. By default, needrestart is now configured to automatically restart services any time apt updates underlying libraries (for example, libssl).

This behaviour is designed to apply security patches to running processes immediately. However, this can cause unplanned downtime for services like cloudera-scm-server.service (the Cloudera Manager Server).

To ensure service stability and to control all restarts, you can disable this automatic behaviour on all production Ubuntu 24.04 hosts. You can use multiple approaches to achieve this, as outlined in the Ubuntu Community Discourse: `needrestart` changes in Ubuntu 24.04: service restarts.

SLES 15 SP6 support for Cloudera Manager

Starting with the Cloudera Manager 7.13.2.0 release, Cloudera Manager provides support for SLES 15 SP6.

SLES 15 SP6 supports only the Python 3.11 version in the Cloudera Manager 7.13.2 release.

Kafka protocol and metadata version is set automatically during upgrades

When upgrading Kafka, Cloudera Manager now automatically sets the inter.broker.protocol.version property for ZooKeeper-based clusters and the metadata.version property for KRaft-based clusters. You no longer need to manually set these properties to the current protocol or metadata version before an upgrade. This feature is only available when upgrading to Cloudera Runtime 7.3.2 or higher.

After the upgrade, clearing these properties remains a manual task. However, in Cloudera Runtime 7.3.2 and higher, both inter.broker.protocol.version and metadata.version are now available for direct configuration in Cloudera Manager > Kafka > Configuration. The label names of the properties are Kafka Inter-Broker Protocol Version and Kafka Metadata Version. This means you can set or clear these properties directly from the UI, without needing to use advanced configuration snippets.
