Question

我正在尝试使用Spark，并在远程运行Scala脚本时遇到错误。

我正在使用Spark 1.4.1，并将此依赖项导入Maven以构建：

<dependency>
  <groupId>org.apache.spark</groupId>
  <artifactId>spark-core_2.10</artifactId>
  <version>1.4.1</version>
</dependency>

这是我正在运行的简化代码：

package test.package

import org.apache.spark.{ SparkConf, SparkContext }

object App {
  def main(args: Array[String]) {
    System.out.println("Setting up Spark..")
    val sparkConf = new SparkConf().setAppName("HBaseRead").setMaster("spark://141.161.88.169:7077")
    val sc = new SparkContext(sparkConf)  // Error occurs here.
    System.out.println("Done!")
  }
}

这是Spark主人的日志中的堆栈跟踪：

它看起来像是配置设置的序列化问题，但它看起来并不像是有什么不同寻常的。

Answer 1

我最近在尝试从连接到我的独立spark集群（版本1.5.2）的eclipse启动spark应用程序时遇到了同样的问题（并得到了完全相同的异常）。发生这种情况是因为我的应用程序pom.xml中使用的库版本与我尝试连接的spark master部署存在冲突。

由于我的应用程序pom.xml最近发生了变化，我开始遇到此问题。我通过评论几个依赖项来使用反复试验，最终它是由于以下条目引起的。

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-library</artifactId>
    <version>2.10.0</version>
</dependency>

我评论了这一切，一切都开始正常。因此，请确保您的spark程序和spark部署的库版本匹配。

Answer 2

在我的情况下，我一直在使用 rdd.unpersist 虽然仍然由不同的线程使用RDD缓存块，但是持久性发生了导致java.io.OptionalDataException 所以我删除了rdd.unpersist代码，并让LRU引发逐出

Answer 3

我可以从简单的应用程序代码中看到

setMaster("spark://141.161.88.169:7077")

但错误消息是：

Association with remote system [akka.tcp://sparkDriver@10.212.142.148:55578] has failed

在我看来，您的主地址不一样......

或者通过“与远程系统的关联失败”检查my answer here与您的问题类似的问题
