Hue is a set of web applications that enable you to interact with a CDH cluster. Hue applications let you browse HDFS, manage a Hive metastore, and run Hive and Cloudera Impala queries, HBase and Sqoop commands, Pig scripts, MapReduce jobs, and Oozie workflows.
Hue applications run in a Web browser and require no client installation.
The following figure illustrates how Hue works. Hue Server is a "container" web application that sits in between CDH and the browser. It hosts all the Hue web applications and communicates with CDH components.
To display the help text for a Hue application, click the Help ( ) tab in the Hue navigation bar,
then click the appropriate link in the Help navigation bar at the top of the Help
window.
To log out of Hue, click Sign Out from the pull-down list under the logged-in user name (at the right of the Hue navigation bar).
If Hue detects a misconfiguration, an indicator appears in the navigation bar at the top of the page.
Clicking this indicator takes you to the Check Configuration screen which will indicate the
potential misconfiguration(s) with hints about fixing them.
You can go directly to your own information by selecting
at the right of the Hue navigation bar.If authentication is managed by Hue (that is, authentication is not managed via some external mechanism), and you are a superuser, you can use the User Admin application to change password and personal details.
The Hue team strongly values your feedback. The best way to contact us is to send email to hue-user@cloudera.org.
If you're experiencing transient errors (typically an error message saying a service is down), contact your system administrator first.
