Question

我正在努力找出我的spark（2.1.0）作业scala依赖项。

我的build.sbt文件：

name := "test"

version := "0.0.1"

scalaVersion := "2.11.0"

libraryDependencies += "org.apache.spark" %% "spark-core" % "2.1.0" % "provided"
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "2.1.0" % "provided"
libraryDependencies += "org.apache.spark" %% "spark-streaming-kinesis-asl" % "2.1.0"
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.5.1"

assemblyJarName in assembly := "test.jar"


mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
  {
    case m if m.toLowerCase.endsWith("manifest.mf") => MergeStrategy.discard
    case m if m.startsWith("META-INF") => MergeStrategy.discard
    case PathList("javax", "servlet", xs @ _*) => MergeStrategy.first
    case PathList("org", "apache", xs @ _*) => MergeStrategy.first
    case PathList("org", "jboss", xs @ _*) => MergeStrategy.first
    case "about.html"  => MergeStrategy.rename
    case "reference.conf" => MergeStrategy.concat
    case _ => MergeStrategy.first
  }
}

exportJars:= true

mainClass in assembly := Some("test.Job")
```

当我开始工作时，会抛出java.lang.NoSuchMethodError个例外。

你在aws emr上运行这个吗？如果是这样，以下链接可能有所帮助：

Spark streaming 1.6.1 is not working with Kinesis asl 1.6.1 and asl 2.0.0-preview http://www.waitingforcode.com/apache-spark/shading-solution-dependency-hell-spark/read

基本上aws EMR支持protobuf 2.5，但是spark-core，spark-streaming和spark-streaming-kinesis-asl版本都依赖于protobuf 2.6.1，当我们遇到它时我们解决这个问题的方式是通过一个带阴影的罐子，上面的两个链接给出了如何设置的好例子。
