在集群模式下运行spark kinesis流媒体应用程序时出错（Amazon EMR）

Question

Spark-submit--class MyClass-master yar--deploy-mode cluster--executor-memory 1g--executor-cores 2 hdfs://url：port/my.jar

这个应用程序，接收来自kinesis流的传入数据，并基于它执行一个请求（回发）到一个我可以跟踪的url。我已经在本地测试了我的应用程序，运行它设置SparkConfig上的Master到本地[核心]。

此外，这里是我的代码和我的构建SBT。我的项目使用的是scala 2.11.8和sbt 0.13.8

name := "my-app"

version := "1.0"

scalaVersion := "2.11.8"

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-streaming_2.11" % "2.0.0" % "provided",
  "org.apache.spark" % "spark-streaming-kinesis-asl-assembly_2.11" % "2.0.0",
  "org.scalaj" % "scalaj-http_2.11" % "2.3.0"
)

assemblyMergeStrategy in assembly := {
  case PathList("org", "apache", xs @ _*) => MergeStrategy.last
  case x =>
    val oldStrategy = (assemblyMergeStrategy in assembly).value
    oldStrategy(x)
}

}

在集群主节点中子密化应用程序后，出现以下错误。

我真的很感激任何关于这个主题的指导，因为我是开发和使用spark应用程序的新手。

本文就Kinesis中的火花流错误给出了解决方法

实际上，我已经用amazon emr 5.2.1建立了集群，它使用Spark 2.0.2并且我绑定了我的胖罐子，使用Spark-Streaming-Kinesis-ASL-Assembly2.11 2.2.0。

因此，我的应用程序无法从Kinesis读取输入数据
