implicits is not a member of org.apache.spark.sql.SQLContext

[Wang, Ningjun (LNG-NPV)]

I tried to convert an RDD to a data frame using the example codes on spark 
website



case class Person(name: String, age: Int)


val sqlContext = new org.apache.spark.sql.SQLContext(sc)
import sqlContext.implicits._

val people  = 
sc.textFile("examples/src/main/resources/people.txt").map(_.split(",")).map(p 
=> Person(p(0), p(1).trim.toInt)).toDF()

It compile fine using sbt. But in IntelliJ IDEA 14.0.3, it fail to compile and 
generate the following error

Error:(289, 23) value implicits is not a member of 
org.apache.spark.sql.SQLContext
    import sqlContext.implicits._
                      ^

What is the problem here? Is there any work around (e.g. do explicit 
conversion)?

Here is my build.sbt

name := "my-project"

version := "0.2"

scalaVersion := "2.10.4"

val sparkVersion = "1.3.1"

val luceneVersion = "4.10.2"

libraryDependencies <<= scalaVersion {
  scala_version => Seq(
    "org.apache.spark" %% "spark-core" % sparkVersion  % "provided",
    "org.apache.spark" %% "spark-mllib" % sparkVersion % "provided",
    "spark.jobserver" % "job-server-api" % "0.4.1" % "provided",
    "org.scalatest" %% "scalatest" % "2.2.1" % "test"
  )
}
