我只是在阅读文本文件并打印计数

val rdd = sparkLocal.read.text("/data/logs/file.log")
println(rdd.count)

但我得到了结果

这是我的 build.sbt

libraryDependencies ++= {
  val akkaVersion = "2.4.10"
  val sparkVersion = "2.1.0"

  Seq(
    "com.typesafe.akka" %% "akka-actor"                           % akkaVersion,
    "org.apache.spark"  %%  "spark-core"                          % sparkVersion,
    "org.apache.spark"  %%  "spark-sql"                           % sparkVersion,
    "org.apache.spark"  %%  "spark-hive"                          % sparkVersion,
    "com.typesafe.akka" %% "akka-slf4j"                           % akkaVersion,
    "org.apache.spark"  %% "spark-streaming"                      % sparkVersion
  )
}

任何人请帮助我

有同样的问题，这似乎是由 this issue of the Janino compiler 引起的.

该问题已关闭，根据 change log该修复程序应包含在 2017 年 3 月 22 日发布的版本 3.0.7 中，该版本已经是 on Maven .

我添加了一个明确的

libraryDependencies += "org.codehaus.janino" % "janino" % "3.0.7"

到我的 build.sbt到目前为止它似乎解决了这个问题。
