pyspark-analytics-workshop

Some helper code to get setup for a workshop on using pyspark for big data analytics

Setup

Create a virtualenv

• cd pyspark-analytics-workshop
• virtualenv -p python3 venv_spark_workshop
• . venv_spark_workshop/bin/activate
• pip install -r requirements.txt
• ipython kernel install --user --name=pyspark-workshop

Starting local pyspark

Start pyspark using a jupyter notebook environment. This should automatically open a browser window. When you start a notebook from here, the spark context will be available in a variable spark.

• cd notebooks
• SPARK_HOME="$(ls -d ../venv_spark_workshop/lib/python*)/site-packages/pyspark" HADOOP_CONF_DIR= PYSPARK_DRIVER_PYTHON=jupyter PYSPARK_DRIVER_PYTHON_OPTS='notebook' pyspark
  • Note: if you have a spark already installed globally, do not set SPARK_HOME here
