Spark – Write Dataset to JSON file Dataset class provides an interface for saving the content of the non-streaming Dataset out into external storage. JSON is one of the many formats it provides. In this tutorial, we shall learn to write Dataset to a JSON file. Steps to Write Dataset to JSON file in Spark To write Spark Dataset to JSON file 1. Requirement Let’s say we have a set of data which is in JSON format. The file may contain data either in a single line or in a multi-line. The requirement is to process these data using the Spark data frame. In addition to this, we will also see how toRead More → How to parse a JSONString To Dataset?

This Spark SQL tutorial with JSON has two parts. Spark SQL can automatically infer the schema of a JSON dataset and load it as a Dataset[Row]. This conversion can be done using SparkSession.read.json() on either a Dataset[String], or a JSON file. Note that the file that is offered as a json file is not a typical JSON file.
