Let’s Big Data. Hue is an open source Web interface for analyzing data with Hadoop and Spark.

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, PostGres, Sqlite and Oracle
• Dynamic search dashboards for Solr
• Spark Notebooks
• Browsers for YARN, HDFS, Hive table Metastore, HBase, ZooKeeper
• Pig Editor, Sqoop2, Oozie workflows Editors and Dashboards
• Wizards to import data into Hadoop

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

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

• openssl (Homebrew)
• Required for Mac OS X 10.11+ (El Capitan), after brew install openssl, run: export LDFLAGS=-L/usr/local/opt/openssl/lib && export CPPFLAGS=-I/usr/local/opt/openssl/include

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.

Hue would not be possible without:
