User authentication in Hue
Cloudera Data Warehouse supports authenticating users to Hue using SAML.
After Hue is authenticated by a service such as Hive, Hue impersonates the user requesting the use of that service, for example, to create a Hive table. In this case, the Hive service uses Apache Ranger to ensure that the group to which the user belonged is authorized for that action (to create a Hive table).
