Welcome to Hue! =============== Hue is a browser based environment for interacting with your Hadoop cluster. You or your system administrator has already installed the system (excellent!); this document will help get you oriented. ## Starting Applications The icons at the bottom of your screen, when clicked, will open different applications (e.g., the file browser or the health dashboard). Double-click to open a second instance of an application. ## Logging in and out The logout link is in the top left of your screen, right after your username. When you log out, Hue will restore the application windows you had open. ## Keyboard Shortcuts To see what keyboard shortcuts are available, type "Ctrl-/" or click on the "command" clover in the top right corner of the screen. ## Changing your password If authentication is managed by Desktop (i.e., it is not configured to authenticate via some other mechanism), the User Manager application allows you to change your password. ## Seeking Help, Reporting Bugs, and Providing Feedback The Hue team strongly values your feedback! The "feedback" link in the bottom right of your screen is the best way to reach us. If you're experiencing transient errors (typically an error message saying a service is down), you may wish to run them by your system administrator first. Every window that's rendered in Hue is typically backed by an HTTP GET or POST request sent to the server via AJAX. If you're familiar with web development, and you're reporting a problem or bug, it's very useful to use Firebug (or similar) to figure out what request is failing, and include that in your bug report. ## Browser Compatibility Hue works best in Firefox, and works well in Chrome and Safari as well. ## Extending Desktop Hue has an SDK to build new applications within the framework. Contact us (again, via the feedback link) if you're interested in building new applications within the framework. ## Help for the Applications Each application installed within Hue may have its own help page(s). The index below directs you there.
