Adding Security Browser to the blocked list of applications

The Security Browser application is no longer supported in Hue on CDP. If you were using Sentry on your CDH cluster and a Security Browser in Hue, then you must manually add the Security Browser application to the list of blocked applications in the Hue Advanced Configuration Snippet after upgrading to CDP.

After upgrading from CDH to CDP, you may see the following error when accessing the Security Browser: “Failed to connect to Sentry server localhost”. To prevent this error:

  1. Log in to Cloudera Manager as an Administrator.
  2. Go to Clusters > Hue service > Configuration > Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini and append security to the app_blacklist property. For example: 
    [desktop]
app_blacklist=pig,spark,security
  3. Click Save Changes.
  4. Restart the Hue service.
