Cloudera Data Warehouse hardware requirements

Review the requirements needed to get started with the Cloudera Data Warehouse (CDW) service on Red Hat OpenShift 4.6 clusters.

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 CDW service requires the "cluster-admin" role on the OpenShift and ECS 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.
