1. Use the bootstrap script on this link to install iPython Notebook: https://github.com/awslabs/emr-bootstrap-actions/tree/master/ipython-notebook
2. Although the iPython server is running, it's not integrated with Spark. Follow the instructions according to this blog post: https://districtdatalabs.silvrback.com/getting-started-with-spark-in-python
3. Create the initial SparkContext and SQL context as follows:

from pyspark import  SparkContext
sc = SparkContext( 'local', 'pyspark')

from pyspark.sql import SQLContext
sqlContext = SQLContext(sc)
