IntelliJ Idea 14: cannot resolve symbol spark

Question

I made a dependency of Spark which worked in my first project. But when I try to make a new project with Spark, my SBT does not import the external jars of org.apache.spark. The

Answer 1

This worked for me->

name := "ProjectName"
version := "0.1"
scalaVersion := "2.11.11"

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.11" % "2.2.0",
  "org.apache.spark" % "spark-sql_2.11" % "2.2.0",
  "org.apache.spark" % "spark-mllib_2.10" % "1.1.0"
)

Answer 2

I had a similar problem. It seems the reason was that the build.sbt file was specifying the wrong version of scala.

If you run spark-shell it'll say at some point the scala version used by Spark, e.g.

Using Scala version 2.11.8

Then I edited the line in the build.sbt file to point to that version and it worked.

Answer 3

name := "SparkLearning"

version := "0.1"

scalaVersion := "2.12.3"

// additional libraries libraryDependencies += "org.apache.spark" % "spark-streaming_2.10" % "1.4.1"

Answer 4

I use

scalaVersion := "2.11.7"

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.4.1"

in my build.sbt and it works for me.

Answer 5

Currently spark-cassandra-connector compatible with Scala 2.10 and 2.11.

It worked for me when I updated the scala version of my project like below:

ThisBuild / scalaVersion := "2.11.12"

and I updated my dependency like:

libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "2.4.0",

If you use "%%", sbt will add your project’s binary Scala version to the artifact name.

From sbt run:

sbt> reload
sbt> compile

Answer 6

Your library dependecy conflicts with with the scala version you're using, you need to use 2.11 for it to work. The correct dependency would be:

scalaVersion := "2.11.7"
libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "1.4.1"

note that you need to change spark_parent to spark_core
