Prerequisites for CDW backup and restore in Private Cloud

Learn about the prerequisites that are mandatory for a successful backup and restore event of Cloudera Data Warehouse (CDW) Data Service.

  • You must have an active CDW cluster with one Database Catalog and one or more Hive or Impala Virtual Warehouses.
  • Only the default Database Catalog is backed up. Ensure that you do not have custom (non-default) Database Catalogs.
  • You have installed and configured CDP CLI version 0.9.99 or higher on a host in your cluster from which you can access CDP Private Cloud Data Services.
  • You have Cluster Administrator privileges and can access the CDW web interface.
  • You must use the same CDW version to restore the files you used during the backup process.

Before you start the backup process, you must deactivate the environment in CDW to ensure successful cluster restoration. During downtime, you must prevent end-users from accessing the cluster.

To deactivate the environment in CDW:

  1. Log in to the Data Warehouse service as a DWAdmin.
  2. Go to the Environments tab on the Overview page, and click Deactivate corresponding to the environment you want to deactivate.
