Easy to use environment with jupyter notebook and apache spark.

Instead of opening jupyter notebook, just copy the preapareSparkEnvironment.sh script into your prefered directory and inside it run:

    $ source preapareSparkEnvironment.sh

Run directly from github:

    $ source <(curl -s https://raw.githubusercontent.com/boyander/runpyspark/master/prepareSparkEnvironment.sh)

It prepare your shell with pyspark configured to use jupyter notebook. After env is ready run pyspark it will open a jupyter notebook.

IMPORTANT: Before running the preapareSparkEnvironment.sh script, ensure you have followed the checklist for your OS.

Checklist for Ubuntu

• Install spark following this medium post
• Create an alias of spark in your home directory or rename the installation to just "spark"

    $ ln -s ~/spark-2.4.0-bin-hadoop2.7 ~/spark

• Ensure you have spark-shell in your $PATH variable (Note: this suposes you are running zsh or oh-my-zsh terminal, if that's not the case or you are not sure, just change .zshrc to .bashrc in the following command).

    $ echo "export PATH=\"\$PATH:$HOME/spark/bin\"" >> ~/.zshrc
    $ source ~/.zshrc

To check it works, you must be able to run spark-shell from your terminal.

Checklist for MacOSX

• You need brew installed
• brew install jq
• brew install spark-shell

Important Notes

• This script uses python3, ensure python3 is installed and running in your terminal.
• When creating a jupyter notebook, ensure you've choosed python 3 kernel, otherwise it will not work.
• There's also a notebook PysparkDemo.ipynb to test apache spark worked.
• In case you've created multiple spark contexts, run $ killall java to stop all apache spark instances.
