Adding Hue service with Cloudera Manager
Hue is a web-based interactive query editor that enables you to interact with databases
and data warehouses. Data architects, SQL developers, and data engineers can use Hue to create
data models, clean data to prepare it for analysis, and to build and test SQL scripts for
Install and configure MySQL database Hue requires a SQL database such as MySQL, PostgreSQL, or Oracle to store small amounts of data, including user account information, query history, and permissions. The instructions in this topic are for installing the MySQL database. Add the Hue service using Cloudera Manager After you have installed and configured the MySQL database for Hue, add the Hue service using Cloudera Manager. Enable Kerberos for authentication For Hue to work properly with a CDP cluster that uses Kerberos for authentication, the Kerberos Ticket Renewer role must be added to the Hue service. After you have added the Hue service to your cluster, renew the Kerberos ticket for Hue and enable Kerberos for authentication. Integrate Hue with Knox You can use the Apache Knox Gateway to interact with Hue REST APIs and the Hue user interface, along with other CDP components and services. To set up Knox Single Sign-on (SSO) to authenticate users, you must configure the KnoxSpnegoDjangoBackend property using Cloudera Manager. Grant Ranger permissions to new users or groups If you have secured your cluster using Ranger, then you must grant proper permissions to your users and groups from the Ranger web interface. If your users do not have proper permissions, then they may not be able to access certain databases or tables from the Hue editor.
