Introduction to Hue Advanced Configuration Snippet (Safety valves)
To customize and configure Hue properties, such as authentication or enabling S3 or ABFS browsers, and so on that you cannot directly configure from the Cloudera Manager UI, you can use the Advanced Configuration Snippet field under the Hue cluster configurations in Cloudera Manager.
Advanced safety valves
The field for hue_safety_valve.ini is service-wide and affects all Hue roles listed on the Instances tab. The field for hue_safety_valve_server.ini only affects Hue Server role instances.
Environment safety valves
Environment safety-valves let you configure environment variables across the service or for specific role instances. These safety-valves lack headers.
