Cloudera Data Warehouse hardware requirements

Review the requirements needed to get started with the Cloudera Data Warehouse service on Red Hat OpenShift.

You can also use the Cloudera Data Services on premises Spreadsheet to model the number and specification of hosts required for a deployment. See How to use the sizing spreadsheet.

  • Cloudera Manager must be installed and running.
  • Cloudera Data Services on premises must be installed and running. See Installing on OpenShift and Installing on ECS for more details.
  • An environment must have been registered with Cloudera Management Console on the on premises. See Cloudera on premises Environments for more details.
  • In addition to the general requirements, Cloudera Data Warehouse also has the following minimum memory, storage, and hardware requirements for each worker node using the standard resource mode:

Depending on the number of executors you want to run on each physical node, the per-node requirements change proportionally. For example, if you are running 3 executor pods per physical node, you require 384 GB of memory and approximately 1.8 TB of locally attached SSD/NVMe storage.

Security requirements

The Cloudera Data Warehouse service requires the "cluster-admin" role on the OpenShift and Cloudera Embedded Container Service cluster in order to install correctly. The "cluster-admin" role enables namespace creation and the use of the OpenShift Local Storage Operator for local storage.
