[spark] Move assist panel to a separate KO component

With this commit the assist panel code is moved to a separate KO component. A new ko_components.mako is created to act as a library for this and future knockout components.

The assist instance is currently shared with codemirror for autocomplete so it currently has to be created from outside the component and passed as a reference. When we move to a new editor we should consider refactoring this as well.

Welcome to the repository for Hue

Hue is an open source Web interface for analyzing data with Apache Hadoop:


It features:

  • File Browser for accessing HDFS
  • Hive Editor for developing and running Hive queries
  • Search App for querying, exploring, visualizing data and dashboards with Solr
  • Impala App for executing interactive SQL queries
  • Spark Editor and Dashboard
  • Pig Editor for submitting Pig scripts
  • Oozie Editor and Dashboard for submitting and monitoring workflows, coordinators and bundles
  • HBase Browser for visualizing, querying and modifying HBase tables
  • Metastore Browser for accessing Hive metadata and HCatalog
  • 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
  • A DB Query Editor for MySql, PostGres, Sqlite and Oracle

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

More user and developer documentation is available at

Getting Started

To build and get the development server running:

$ git clone
$ 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/ 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

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:

for Python/Django code
for configuration (.ini) files to be installed
for static HTML/js resources and help doc
for data to be put through a template engine
for localizations in multiple languages

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