# Starts a Jupyter Notebook Server with a PySpark Kernel.
# to run, SPARK_HOME must be set and point to a Spark installation
# or run from the Spark installation directory.

# Alternatively, as a single command instead of the script:
# $ PYSPARK_DRIVER_PYTHON=jupyter PYSPARK_DRIVER_PYTHON_OPTS='notebook' $SPARK_HOME/bin/pyspark

# Use current directory if SPARK_HOME not set
if [ -z "${SPARK_HOME}" ]; then
   export SPARK_HOME="$(dirname "$0")"
fi

export PYSPARK_DRIVER_PYTHON=jupyter
export PYSPARK_DRIVER_PYTHON_OPTS='notebook'

exec "${SPARK_HOME}"/bin/pyspark "$@"

There are lots of ways to start Jupyter with a PySpark kernel, depending on your use case. When I want to quickly try something out locally on my laptop, the above script works for me.
