Welcome to the repository for Hue

Dynamic Search dashboards with Solr
Spark and Hadoop notebooks
Scheduling of jobs and workflows through an Oozie Editor and Dashboard

More user and developer documentation is available at gethue.com.

Getting Started

To build and get the development server running:

$ git clone https://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:

Install the mini cluster (only once):

$ ./tools/jenkins/jenkins.sh slow

Run all the tests:

$ build/env/bin/hue test all

Or just some parts of the tests, e.g.:

$ build/env/bin/hue test specific impala
$ build/env/bin/hue test specific impala.tests:TestMockedImpala
$ build/env/bin/hue test specific impala.tests:TestMockedImpala.test_basic_flow

Docker

Start Hue in a single click with the Docker Guide or the video blog post.

File Layout

The Hue "framework" is in desktop/core/ and contains the Web components. desktop/libs/ is the API for talking to various Hadoop services. 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.
