# jupyter-spark

[](https://travis-ci.org/mozilla/jupyter-spark)

[](https://codecov.io/gh/mozilla/jupyter-spark)

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.

## Installation

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 `

You may also have to enable the widgetsnbextension extension if it hasn’t been enabled before (check by running jupyter nbextension list):

` jupyter nbextension enable --py widgetsnbextension `

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

` jupyter nbextension list jupyter serverextension list `

Pleaes feel free to install [lxml](http://lxml.de/) 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 `

## Configuration

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" `
