sparksession config
Creating a SparkSession. In previous versions of Spark, you had to create a SparkConf and SparkContext to interact with Spark, as shown here: //set up the spark configuration and create contexts val sparkConf = new SparkConf().setAppName("SparkSessi, In simple terms, values set in "config" method are automatically propagated to both SparkConf and SparkSession's own configuration. for eg : you can refer to https://jaceklaskowski.gitbooks.io/mastering-apache-spark/content/spark-sql-settin, Application name can be accessed using SparkContext : spark.sparkContext.appName.
