Error on integrating Spark with Scala project in IntelliJ IDE

Question

I created a simple SBT project in IntelliJ IDE with the following library dependencies in build.sbt :

import _root_.sbt.Keys._

name := "untitled"

version := "1.0"

scalaVersion := "2.11.7"

libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-core" % "1.5.1",
  "org.apache.spark" %% "spark-sql" % "1.5.1" ,
  "org.apache.spark" %% "spark-mllib"  % "1.5.1")

The objective is to import Spark and MLLIB of Spark, and then to create a Scala object as explained here .

However, the following error occurs on importing:

 SBT project import [warn] Multiple dependencies with the same organization/name but different versions. To avoid conflict, pick one version: [warn] *

Answer 1

Spark will not work with Scala 2.11. It uses Scala 2.10, so you need to use a compatible Scala version (see http://spark.apache.org/docs/latest/ ).

Alternatively, you can, as @eliasah has also mentioned in a comment, build Spark yourself. Instructions on how to build Spark can be found at http://spark.apache.org/docs/latest/building-spark.html
