We will work with Spark 2.1.0 and I suppose that the following are installed: This version of Java introduced Lambda Expressions which reduce the pain of writing repetitive boilerplate code while making the resulting code more similar to Python or Scala code. Sparkour Java examples employ Lambda Expressions heavily, and Java 7 support may go away in Spark 2.x. Every sample example explained here is tested in our development environment and is available at PySpark Examples Github project for reference. All Spark examples provided in this PySpark (Spark with Python) tutorial is basic, simple, and easy to practice for beginners who are enthusiastic to learn PySpark and advance your career in BigData and Machine Learning. Debugging Spark is done like any other program when running directly from an IDE, but debugging a remote cluster requires some configuration. On the machine where you plan on submitting your Spark job, run this line from the terminal: export SPARK_JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8086 *** Apache Spark and Scala Certification Training- https://www.edureka.co/apache-spark-scala-certification-training ***This Edureka video on "Spark Java Tut Java Programs | Java Programming Examples.
