CDP Private Cloud Data Services Software Requirements

The software requirements for the nodes on which CDP Private Cloud Data Services are deployed are identical to CDP Private Cloud Base. The most basic requirement is the operating system and JDK support.

This release ships with Cloudera Manager 7.6.5. This new version of Cloudera Manager has the support to create and manage the ECS cluster. If you have an existing Base cluster setup, managed by Cloudera Manager, you must first upgrade Cloudera Manager to version 7.6.5.

For this release, the ECS nodes will support:

• CentOS 8.4, 7.9, Red Hat Enterprise Linux 8.4. 7.9, Oracle Linux 7.9, and CentOS 8.2 (CDW only)

• JDK 11 (any distribution)
• For CML, you must install nfs-utils in order to mount longhorn-nfs provisioned mounts. The nfs-utils package is required on every node of the ECS cluster. Run this command yum install nfs-utils to install nfs-utils.
• If you have nodes with GPU, ensure that the GPU hosts have nVidia Drivers and nvidia-container-runtime installed. You must confirm that drivers are properly loaded on the host by executing the command nvidia-smi. You must also install the nvidia-container-toolkit package.

Additionally, you must perform the following:

• You must have a minimum of one agent node for ECS.
• Set up Kerberos on these clusters using an Active Directory or MIT KDC.
• Enable TLS on the Cloudera Manager cluster for communication with components and services.
• Configure PostgreSQL database as an external database for the Private Cloud Base cluster components^*.
• If you do not have entitlements, contact your Cloudera account team to get the necessary entitlements.
• The default docker service uses /docker folder. Whether you wish to retain /docker or override /docker with any other folder, you must have a minimum of 200 GB space.
• Ensure all the hosts in the ECS cluster have 100 gigabytes free in the /var/lib directory at the time of installation.
• The cluster generates multiple hosts and host based routing is used in the cluster in order to route it to the right service. You must decide on a domain for the services which Cloudera Manager by default points to one of the hostnames on the cluster. However, during the installation, you should check the default domain and override the default domain (only if necessary) with what you plan to use as the domain. The default domain must have a wildcard DNS entry. For example, “*.apps.myhostname.com”.
• It is recommended that you leave IPv6 enabled at the OS level on all ECS nodes.
