Spark is built on the concept of distributed datasets, which contain arbitrary Java or Python objects. You create a dataset from external data, then apply parallel operations to it. The building block of the Spark API is its RDD API.
This program just counts the number of lines containing ‘a’ and the number containing ‘b’ in a text file. Note that you’ll need to replace YOUR_SPARK_HOME with the location where Spark is installed. As with the Scala and Java examples, we use a SparkContext to create RDDs.
When using spark-submit shell command the spark application need not be configured particularly for each cluster as the spark-submit shell script uses the cluster managers through a single interface. Download and install Gradle Step 1: create a basic Java application with Gradle First, create a directory, and run gradle init, specify 2 for application, 3 for Java language, and specify others as Spark has added an Optional class for Java (similar to Scala’s Option) to box values and avoid nulls. There is a special function isPresent () in the Optional class that allows to check whether the value is present, that is it is not null. Calling get () returns the boxed value. The spark-submit command is a utility to run or submit a Spark or PySpark application program (or job) to the cluster by specifying options and configurations, the application you are submitting can be written in Scala, Java, or Python (PySpark) code. You can use this utility in order to do the following. Basics Spark’s shell provides a simple way to learn the API, as well as a powerful tool to analyze data interactively.
