What's new in Cloudera Data Services on premises 1.5.5

Understand the functionalities and improvements to features of Cloudera Control Plane install and upgrade components in Cloudera Data Services on premises 1.5.5.

Certificate Management

Cert-manager is an open-source tool for Kubernetes that automates the provisioning, management, and renewal of TLS certificates. Its documentation at https://cert-manager.io/docs/ provides comprehensive guidance on installing, configuring, and using cert-manager to secure workloads with trusted X.509 certificates. Cloudera provides out-of-the-box support for Venafi Trust Protection Platform (TPP) as part of the Cloudera Cloudera Embedded Container Service installation. By integrating cert-manager, the Data services achieve secure communication, reduced manual overhead, and compliance with security standards, leveraging its robust automation and flexibility. For more information on setting Cert-manager using Venafi TPP, see Setting up Certification Manager using Venafi TPP.

New upgrade prechecks

New pre-upgrade checks have been added to the list. The additional checks verify if the control plane and the docker registry is ready for upgrade. For more information, see Pre-upgrade checklist.

Quota Management for multiple base cluster support

Quota management enables you to control how resources are allocated within your Cloudera Data Services on premises clusters. In order to prevent a single workload from consuming all available cluster resources, you can limit the number of CPUs, GPUs, and memory allocated by application, user, business units, or Data Service by defining resource pools that define resource limits. Pools are organized in a hierarchical manner by defining nodes in the hierarchy with resource limits, which can then be subdivided as needed to allocate resources for an organization and to allocate resources to cluster or environment wide services such as the monitoring service. For information, see Quota Management.

Creating multiple environments with different base or Data Lake clusters

To register an environment with a data lake cluster managed by a Cloudera Manager that is different from your existing Cloudera Manager, you need to add the certificates of the new Cloudera Manager to the Cloudera Management Console UI. If the existing Cloudera Manager and the new Cloudera Manager share the same root CA, and the root CA is already uploaded as the data lake certificate, then no additional certificate needs to be added. For more information, see Creating multiple environments with different base or Data Lake clusters.
