Welcome to the repository for Hue

Hue is an open source Web interface for analyzing data with any Apache Hadoop: gethue.com

It features:

• SQL editors for Hive, Impala, MySQL, Oracle, PostgreSQL, SparkSQL, Solr SQL, Phoenix...
• 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.
