Cloudera Navigator Data Management Component UI

The Cloudera Navigator data management component UI is the web-based UI that you use to:
  • Create and view audit reports
  • Search entity metadata, view entity lineage, and modify business metadata
  • Define policies for modifying custom metadata when entities are extracted
  • Assign user roles to groups

Navigator auditing, lineage, metadata, and policies all support multi-cluster deployments that are managed by a single Cloudera Manager instance. So if you have five clusters, all centrally managed by a single Cloudera Manager, you'll see all this information within a single Navigator data management component UI. In the metadata portion of the UI, Navigator also tracks the specific cluster the data comes from with the Cluster technical metadata property.

    • Enter the URL of the Navigator UI in a browser: http://Navigator_Metadata_Server_host:port/, where Navigator_Metadata_Server_host is the name of the host on which you are running the Navigator Metadata Server role and port is the port configured for the role. The default port of the Navigator Metadata Server is 7187. To change the port, follow the instructions in Configuring the Navigator Metadata Server Port.
