# Welcome to Hue!

Hue is a browser-based environment that enables you to interact with a Hadoop cluster. Hue includes several easy to use applications that help you work with Hadoop MapReduce jobs, Hive queries, and user accounts. The Hue applications run in a Web browser and require no client installation.

### Starting Applications

To open a Hue application, click the appropriate tab in the navigation bar at the top of the Hue web browser window. To open a second application concurrently (or a second instance of the same application), open it in a new tab (right-click on the tab and select "Open link in new tab").

### Displaying Help for the Hue Applications

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.

### Logging In and Out

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).

### Notice of Misconfiguration

If Hue detects a misconfiguration, an indicator appears in the navigation bar at the top of the page. Clicking this takes you to the Check for misconfiguration page which will indicate the potential misconfiguration(s) with hints about fixing them.

### Changing your Password

If authentication is managed by Hue (that is, authentication is not managed via some external mechanism), you can use the User Admin application to change your password. You can go directly to your own information by selecting Profile under the logged-in user name at the right of the Hue navigation bar. For more information, see the User Admin Help.

### Seeking Help, Reporting Bugs, and Providing Feedback

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.

### Browser Compatibility

Hue works in Chrome, Firefox, and Safari. Internet Explorer 8 and 9 are also supported.
