sparkSQL 的 SBT 依赖项

Question

我开始学习 spark sql 我在 sbt 中使用以下依赖项。我收到错误

name := "sparkLearning"

version := "1.0"

scalaVersion := "2.11.8"

val sparkVersion = "1.6.1"
val sqlVersion = "1.3.1"

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

我收到一个错误。

请告诉我如何解决这个问题。

你的 sbt 文件的正确格式是

name := "sparkLearning"

version := "1.0"

scalaVersion := "2.11.8"

val sparkVersion = "1.6.1"

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.10" % sparkVersion,
  "org.apache.spark" % "spark-sql_2.10" % sparkVersion
  )

我建议您使用应该与 scala 2.11.8 兼容的最新 spark 版本

name := "sparkLearning"

version := "1.0"

scalaVersion := "2.11.8"

val sparkVersion = "2.2.0"

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