SparkConf Example using Spark with Scala

//Without SparkConf

package myPackage

import org.apache.spark.sql.SparkSession

object my1st {

  def main(args:Array[String]) : Unit = {

    val spark = SparkSession.builder()

      .master("local[2]")

      .appName("Ex")

      .getOrCreate()

    val df = spark.read.format("json").load("D:/Ex/Spark-Tutorials-master/data/people.json")

    df.printSchema()

    df.show()

  }

}

//With SparkConf

package myPackage

import org.apache.spark.SparkConf

import org.apache.spark.sql.SparkSession

object my1st {

  def main(args:Array[String]) : Unit = {

    val sparkAppConf = new SparkConf()

    sparkAppConf.set("spark.app.name","Ex")

    sparkAppConf.set("spark.master","local[3]")

    val spark = SparkSession.builder()

      .config(sparkAppConf)

      .getOrCreate()

    val df = spark.read.format("json").load("D:/Ex/Spark-Tutorials-master/data/people.json")

    df.printSchema()

    df.show()

  }

}
