Enabling cache-control HTTP headers when using Hue

You can enable Hue to use HTTP headers such as Cache-Control, Pragma, and Expires to ensure that your broswer always uses the fresh version of the resource. You must set the value of the custom_cache_control property to true in Hue's Advanced Configuration Snippet.

  1. Log in to the CDP web interface as an Administrator.
  2. Go to Management Console > Environments, select your environment and go to the Data Lake tab.
  3. Click on the CM URL to open Cloudera Manager.
  4. Go to Clusters > Hue > Configuration and add the following line in the Hue Service Advanced Configuration Snippet (Safety Valve) for hue_safety_valve.ini field: 
    [desktop]
custom_cache_control=true
  5. Click Save Changes.
  6. Restart the Hue service.
