Jupyter Notebook extension for Apache Spark integration.

Includes a progress indicator for the current Notebook cell if it invokes a Spark job. Queries the Spark UI service on the backend to get the required Spark job information.

To view all currently running jobs, click the "show running Spark jobs" button, or press Alt+S.

A proxied version of the Spark UI can be accessed at http://localhost:8888/spark.

To install, simply run:

pip install jupyter-spark
jupyter serverextension enable --py jupyter_spark
jupyter nbextension install --py jupyter_spark
jupyter nbextension enable --py jupyter_spark
jupyter nbextension enable --py widgetsnbextension

The last step is needed to enable the widgetsnbextension extension that Jupyter-Spark depends on. It may have been enabled before by a different extension.

You may want to append --user to the commands above if you're getting configuration errors upon invoking them.

To double-check if the extension was correctly installed run:

jupyter nbextension list
jupyter serverextension list

Pleaes feel free to install lxml as well to improve performance of the server side communication to Spark using your favorite package manager, e.g.:

pip install lxml

For development and testing, clone the project and run from a shell in the project's root directory:

pip install -e .
jupyter serverextension enable --py jupyter_spark
jupyter nbextension install --py jupyter_spark
jupyter nbextension enable --py jupyter_spark

To uninstall the extension run:

jupyter serverextension disable --py jupyter_spark
jupyter nbextension disable --py jupyter_spark
jupyter nbextension uninstall --py jupyter_spark
pip uninstall jupyter-spark

To change the URL of the Spark API that the job metadata is fetched from override the Spark.url config value, e.g. on the command line:

jupyter notebook --Spark.url="http://localhost:4040"

• Rewrote proxy to use an async Tornado handler and HTTP client to fetch responses from Spark.

• Simplified proxy processing to take Amazon EMR proxying into account

• Extended test suite to cover proxy handler, too.

• Removed requests as a dependency.

• Refactored to fix a bunch of Python packaging and code quality issues

• Added test suite for Python code

• Set up continuous integration: https://travis-ci.org/mozilla/jupyter-spark

• Set up code coverage reports: https://codecov.io/gh/mozilla/jupyter-spark

• Added ability to override Spark API URL via command line option

• IMPORTANT Requires manual step to enable after running pip install (see installation docs)!

  To update:

  1. Run pip uninstall jupyter-spark
  2. Delete spark.js from your nbextensions folder.
  3. Delete any references to jupyter_spark.spark in jupyter_notebook_config.json (in your .jupyter directory)
  4. Delete any references to spark in notebook.json (in .jupyter/nbconfig)
  5. Follow installation instructions to reinstall

• Initial release with a working prototype
