Hue configurations in CDP Runtime

Cloudera Manager exposes properties that allow you to insert custom configuration text into XML configuration, property, and text files, or into an environment. The configuration snippet mechanism is intended for use in cases where there is a configuration setting that is not exposed as a configuration property in the Cloudera Manager web interface. Configuration snippets generally override normal configuration. You can configure custom properties for Hue by specifying them in the Advanced Configuration Snippet (Safety valve) field in Cloudera Manager.

The following table lists the safety valve parameters supported by Hue in Cloudera Data Warehouse:
Parameter Description 
[[desktop]]
app_blacklist

[desktop]
   [[session]]
    ttl=[***NUMBER-OF-SECONDS***]
 Used to configure the duration of a user session. The ttl property determines the length of time that the cookie with the user's session ID lives before expiring. After the ttl setting is reached, the user's session expires whether it is active or not.

The default setting for ttl is 1,209,600 seconds, which equals two weeks.
