我有一个带子项目的sbt项目。他们都使用Scala 2.11.4。在其中一个子项目（sparktest）中，我添加了spark-core
name := """sparktest"""
version := "1.0-SNAPSHOT"
scalaVersion := "2.11.4"
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "1.2.1"
exclude("org.slf4j", "slf4j-log4j12")
)
sparktest取决于另一个名为commons的sbt项目，它将akka-actors重写为2.3.9
问题是，当我尝试运行以下代码段（从火花示例中提取）
import org.apache.spark.{SparkContext, SparkConf}
import scala.math.random
object SparkSpike extends App {
val conf = new SparkConf().setAppName("Spark Pi").setMaster("local")
val spark = new SparkContext(conf)
val slices = if (args.length > 0) args(0).toInt else 2
val n = math.min(100000L * slices, Int.MaxValue).toInt // avoid overflow
val count = spark.parallelize(1 until n, slices).map { i =>
val x = random * 2 - 1
val y = random * 2 - 1
if (x*x + y*y < 1) 1 else 0
}.reduce(_ + _)
println("Pi is roughly " + 4.0 * count / n)
spark.stop()
}
我收到以下错误：

注意：相同的设置适用于新项目。它必须与我现有的项目冲突，这是我想要与spark集成的项目
答案 0 :(得分：11)
答案 1 :(得分：0)
如果出现同样的问题，我的类路径上有几个库 - 一个需要scala 2.10.4，其余的是2.10.6，一旦我在项目级别设置scalaVersion，问题就消失了：
scalaVersion := "2.10.6"
