Standard resource mode requirements

Review the requirements needed to get started with the Cloudera Data Warehouse (CDW) service on Red Hat OpenShift 4.6 and Embedded Container Service (ECS) clusters using the standard resource mode.

• CDP Cloudera Manager must be installed and running.
• CDP Private Cloud must be installed and running. See Private Cloud Installation Overview and Requirements for more details.
• An environment must have been registered with Management Console on the private cloud. See CDP Private Cloud Environments for more details.
• In addition to the general requirements listed in the Private Cloud Installation Requirements documentation, CDW also has the following minimum memory, storage, and hardware requirements for each OpenShift 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 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.
