How to Enable Governance-Based Data Discovery

As of Cloudera Enterprise 5.11, Hue can use the metadata tagging, indexing, and search features available with Cloudera Navigator data management. After integrating Hue with Cloudera Navigator, existing Cloudera Navigator tags and indexed entities can be accessed and viewed in Hue, and entities can be tagged using Hue interfaces. Managed metadata and custom metadata tags created or applied using Hue are then stored in the Cloudera Navigator instance. This How To shows administrators how to enable this capability and SQL users how to use the feature.

Administrator Setup Tasks

Enabling Cloudera Navigator for Hue

To use Hue with Cloudera Navigator, you must give the Hue server access to the Navigator Administrator account and enable the integration by configuring some properties using the Cloudera Manager Admin Console.

Requirements

Follow the steps below to integrate Cloudera Navigator and the Hue server. These steps require Cloudera Navigator to already be installed, configured, and running in the context of a Cloudera Manager cluster. See Cloudera Data Management Guide for more information about Cloudera Navigator.

The administrator performing the configuration tasks must have the Cloudera Manager user role of Navigator Administrator or Full Administrator. Use the same account that was used to set up authentication for Cloudera Navigator users and groups.

  1. Log in to the Cloudera Manager Admin Console.
  2. Select Clusters > Hue.
  3. Click the Configuration tab.

  5. Select Cloudera Navigator from the Category filter. The properties for Cloudera Navigator configuration for Hue display:
    1. Click the Enable Navigator Metadata Server Integration box.

      • Cloudera Manager
      • LDAP (Active Directory, OpenLDAP)
      • SAML (for SSO support)
    3. Click Enable Audit Collection
  6. Click Save Changes.
