Spark exception with java.lang.ClassNotFoundException: de.un

Question

我正在运行SPARK版本2.1.0，并且我会得到以下异常。我得到了结果，但正在抛出例外

我只是读文本文件并打印count

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

但是我得到了结果

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

Answer 1

有相同的问题，这似乎是由Janino编译器的这个问题引起的。

该问题已关闭，根据更改日志，修复程序应包含在2017-03-22发布的版本3.0.7中，该版本已在Maven上。

我添加了一个显式

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

到我的build.sbt，到目前为止，它似乎可以解决这个问题。

Answer 2

val rdd = sc.textfile（"/data/logs/file.log"）println（rdd.count）
