Spark 2.0 missing spark implicits

There is no package called spark.implicits.

With spark here it refers to SparkSession. If you are inside the REPL the session is already defined as spark so you can just type:

import spark.implicits._

If you have defined your own SparkSession somewhere in your code, then adjust it accordingly:

val mySpark = SparkSession
  .builder()
  .appName("Spark SQL basic example")
  .config("spark.some.config.option", "some-value")
  .getOrCreate()

// For implicit conversions like converting RDDs to DataFrames
import mySpark.implicits._
