How to make base cluster configuration changes

In general, as Administrator you perform the following steps:
  1. Make the necessary configuration changes in the base cluster.
  2. Restart the base cluster.
  3. In the Private Cloud compute cluster, run the specific kubernetes commands to restart the pods for CDE after identifying the correct CDE Service namespace.

Identifying the CDE Namespace

  1. Navigate to the Cloudera Data Engineering Overview page by clicking the Data Engineering tile in the Cloudera Data Platform (CDP) management console.
  2. In the CDE Services column, click the Service Details for the CDE service.
  3. Note the Cluster ID shown in the page. For example, if the Cluster ID is cluster-abcd1234, then the CDE Namespace is dex-base-abcd1234.
  4. Use this CDE Namespace (in the above example, it is dex-base-abcd1234) in the following instructions to run kubernetes commands.

Embedded Container Service

  1. Access Cloudera Manager.
  2. Navigate to the Experiences Cluster ECS Web UI: Clusters > Your embedded Cluster > ECS > Web UI > ECS Web UI > .
  3. Select the CDE namespace obtained previously on the top left dropdown.
  4. Navigate to Workloads > Deployments.
  5. Locate dex-base-configs-manager in the list and click Restart from the breadcrumbs on the right.

OpenShift Container Platform

Access the openshift cluster with oc or kubectl, and scale the deployment of dex-base-configs-manager down and back up. Use the following commands:

oc scale deployment/dex-base-configs-manager --namespace <CDE Namespace> --replicas 0
oc scale deployment/dex-base-configs-manager --namespace <CDE Namespace> --replicas 1
