Welcome to the repository for Hue

Hue is both a Web UI for Hadoop and a framework to create interactive Web applications. It features:

• File Browser for accessing HDFS
• Beeswax application for executing Hive queries
• Impala App for executing Cloudera Impala queries
• Oozie App for submitting and monitoring workflows, coordinators and bundles
• Pig Editor for submitting Pig scripts
• HBase Browser for exploring and modifying HBase tables and data
• Table Browser for accessing Hive metadata and HCatalog
• Search app for querying Solr and Solr Cloud
• Job Browser for accessing MapReduce jobs (MR1/MR2-YARN)
• Job Designer for creating MapReduce/Streaming/Java jobs
• A Sqoop 2 editor and dashboard
• A ZooKeeper browser and editor

On top of that, a SDK is available for creating new apps integrated with Hadoop.

More user and developer documentation is available at http://gethue.com.

Getting Started

To build and get the core server running:

$ git clone http://github.com/cloudera/hue.git
$ cd hue
$ make apps
$ build/env/bin/hue runserver

Now Hue should be running on http://localhost:8000 !

The configuration in development mode is desktop/conf/pseudo-distributed.ini.

Note: to start the production server (but lose the automatic reloading after source modification):

$ build/env/bin/supervisor

To run the tests:

$ build/env/bin/hue test all
$ build/env/bin/hue test specific filebrowser
$ build/env/bin/hue test specific jobbrowser.tests:test_get_path

File Layout

The Hue "framework" is in desktop. /core/ contains the Web components and desktop/libs/ the API for talking to Hadoop. The installable apps live in apps/. Please place third-party dependencies in the app's ext-py/ directory.

The typical directory structure for inside an application includes:

src/

for Python/Django code

models.py urls.py views.py forms.py settings.py

conf/

for configuration (.ini) files to be installed

static/

for static HTML/js resources and help doc

templates/

for data to be put through a template engine

locales/

for localizations in multiple languages

For the URLs within your application, you should make your own urls.py which will be automatically rooted at /yourappname/ in the global namespace. See apps/about/src/about/urls.py for an example.
