Spark on Kubernetes. Prerequisites. This feature makes use of native Kubernetes scheduler that has been added to Spark. GitHub is where people build software. Spark for Kubernetes. To create the Spark pods, follow the steps outlined in this GitHub repo. Spark In this class, we cover the Apache Spark framework, explaining Resilient Distributed Datasets, SparkSQL, Spark MLLib, and how to interact with a Spark cluster. I hope you enjoyed this tutorial. Kubernetes is a fast growing open-source platform which provides container-centric infrastructure. Build the image: $ eval $(minikube docker-env) $ docker build -f docker/Dockerfile -t spark-hadoop:3.0.0 ./docker Slides available on the LMS.
