How can I get the current SparkSession in any place of the codes?

Question

I have created a session in the main() function, like this:

val sparkSession = SparkSession.builder.master(\"local[*]\").appName(\"Simple Applic         


        

Answer 1

When SparkSession variable has been defined as

val sparkSession = SparkSession.builder.master("local[*]").appName("Simple Application").getOrCreate()

This variable is going to point/refer to only one SparkSession as its a val. And you can always pass to different classes for them to access as well as

val newClassCall = new NewClass(sparkSession)

Now you can use the same sparkSession in that new class as well.
