ClassNotFoundException scala.runtime.LambdaDeserialize when spark-submit

Question

I follow the Scala tutorial on https://spark.apache.org/docs/2.1.0/quick-start.html

My scala file

/* SimpleApp.scala */
import org.apache.spark.Spark         


        

Answer 1

as @Alexey said, change Scala version to 2.11 fixed the problem.

build.sbt

name := "Simple Project"

version := "1.0"

scalaVersion := "2.11.11"

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.2.0" 

Note that Scala version MUST MATCH with Spark. Look at the artifactId, spark-core_2.11 mean it was compatible with scala 2.11 (No backward or forward compatible)
