java - 在 IntelliJ IDE 中将 Spark 与 Scala 项目集成时出错

Question

我在 IntelliJ IDE 中创建了一个简单的 SBT 项目，在 build.sbt 中包含以下库依赖项:

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")

目标是导入 Spark 和 Spark 的 MLLIB，然后按照说明创建 Scala 对象 here .

但是导入时出现以下错误:

Answer 1

Spark 不适用于 Scala 2.11。它使用 Scala 2.10，因此您需要使用兼容的 Scala 版本(请参阅 http://spark.apache.org/docs/latest/ )。

或者，正如 @eliasah 在评论中提到的那样，您也可以自己构建 Spark。有关如何构建 Spark 的说明可以在 http://spark.apache.org/docs/latest/building-spark.html 找到。
