dockerized_spark_cluster_notebook

Interfacing a spark cluster through a python notebook, dockerized.

Spark master web ui at http://127.0.0.1:8080/
Each worker web ui is on a port assigned by docker so that the number of workers can be scaled up, their port can be found with docker container ls.

Get to the notebook via http://<hostname>:8888/?token=<token>
Check the notebook logs (docker logs notebook) for the token or the direct link. Once inside the notebook, connect with:

from pyspark.sql import SparkSession

spark = SparkSession.builder \
    .master("spark://spark-master:7077") \
    .appName("Spark Swarm") \
    .getOrCreate()

Also working in swarm mode as of Docker version 19.03.4, build 9013bf583a.
