Validating and preparing Data Lake upgrades

You can perform validation and preparation prior to starting the Data Lake upgrade to verify that the upgrade will complete successfully without performing any changes or causing downtime.

During the validation phase,a series of checks are completed to identify the most common issues that could lead to an upgrade failure. Once validation is finished, the preparation phase starts, where the Cloudera Manager packages, parcel files and Custom Service Descriptor (CSD) files are downloaded.

Cloudera Management Console steps

  1. Navigate to your Cloudera on cloud environment.
  2. Click Data Lake > Upgrade on the environment’s page.
  3. Select the new Cloudera Runtime version
  4. Click Prepare and Validate.

A success message is shown if the validation and preparation is successful.

In case the validation and preparation failed, navigate to the Event History to review the cause of the failure. After fixing the issue, you can run the validation and preparation process again.

CDP CLI steps

You can use the following command to validate and prepare the Data Lake upgrades with CDP CLI:
cdp datalake  prepare-data-lake-upgrade --datalake [***ENVIRONMENT CRN***]

You can specify a target Cloudera Runtime image using the --image-id option.

The command returns the operation details, which can be queried using the cdp environments get-operation --operation-id [***OPERATION ID***] command. In case the validation and preparation failed, navigate to the Event History page in Cloudera Management Console to review the cause of the failure. After fixing the issue, you can run the validation and preparation process again.
