Prerequisites for accessing Cloudera Data Explorer (Hue) tables and databases

Cloudera Data Explorer (Hue) is a part of the Cloudera Data Warehouse service. Before you can access Data Explorer (Hue) from Cloudera Data Catalog, you must set up the Cloudera Data Warehouse service.

You must have the DWAdmin role to perform these tasks. For more information, see Granting Cloudera users and groups access to CDW.

  1. Set up an AWS or Azure environment in Cloudera Data Warehouse that has been activated and registered in the Cloudera Management Console:
    Activating an AWS or Azure environment in Cloudera Data Warehouse enables using the existing Data Lakes that are present in the environment. This also creates a default Database Catalog that is used by a Virtual Warehouse.

    For more information, see Activating AWS environments or Activating Azure environments. Currently, Cloudera Data Warehouse only supports AWS and Azure Cloud environments

  2. Set up a Hive or an Impala Virtual Warehouse created using Cloudera Data Warehouse. Depending on your data set type, create a Hive or an Impala Virtual Warehouse using Cloudera Data Warehouse.
    For more information, see Adding a new Virtual Warehouse.
  3. Select the asset type.

    The asset type must be either a Hive Table or Hive DB.

    After these conditions are met, Data Explorer (Hue) links for the selected assets are displayed in Cloudera Data Catalog.
