Importing spark.implicits._ in scala

Question

I am trying to import spark.implicits._ Apparently, this is an object inside a class in scala. when i import it in a method like so:

def f() = {
  val spark          


        

Answer 1

Well, I've been re-using existing SparkSession in each called method.. by creating local val inside method -

val spark: org.apache.spark.sql.SparkSession = org.apache.spark.sql.SparkSession.active

And then

import spark.implicits._
