Installing DataPlane
Also available as:

Knox is not set up on the HDP cluster, or Ambari credentials are incorrect for 'seeded user' mode

This error occurs when the cluster is reachable, but authentication is failing.

Sample Message:

Unable to connect, please retry. DataPlane could not retrieve cluster information.

Possible Causes:
  • Knox is not set up on the cluster.
  • The user wants to use the less secure 'seeded user' mode, but the credentials of the seeded user (user name or password) are not setup in DataPlane.
  1. Validate that Knox is configured correctly as per documentation.
  2. If seeded user mode is being used (for evaluation purposes), add the correct credentials to DataPlane using ./ utils update-user ambari.
