在yarn-client master中以编程方式运行Spark'task'时出现ClassNotFoundException

标签： playframework apache-spark playframework-2.0

我正在尝试将Spark与在Play中运行的Web UI集成。我们的想法是访问HDFS中的处理结果文件（format = parquet），并使用Spark的SparkContext和SQLContext执行不同的任务，然后将转换后的数据提供给UI。

集群以分布式模式运行，它功能齐全，并且已经设置了Hadoop 2.6和Spark 1.5.1。 提交的工作如下：

spark-submit --master yarn --deploy-mode client --num-executors 25 --executor-cores 1 --executor-memory 1g --driver-memory 1g --class ...

产生预期结果，不会引起任何问题。

作为Spark / Play集成的一部分，定义了简单的测试用例来检查SparkContext创建的正确性。

trait SparkOutBehaviour {
 this: FlatSpec =>

 def checkContext(): Unit = {
   it should "create spark context and do simple map" in {
    val conf = new SparkConf()
      .setAppName("DWUI")
      .setMaster("yarn-client")
      .setSparkHome("/workspace/spark")
      .set("spark.ui.enabled", "false")
      .set("spark.yarn.jar", "hdfs:///spark/lib/spark-assembly-1.5.1-hadoop2.6.0.jar")
      .set("spark.logConf", "true")

    val sc = new SparkContext(conf)
    val data = sc.parallelize(1 to 100)
    data.map(math sqrt _).collect().foreach(println)
  }
 }
}

为了能够执行此代码，已添加到build.sbt 

unmanagedClasspath in Test += file("/workspace/hadoop/etc/hadoop")

此测试的执行失败，下面的堆栈跟踪失败。

非常欢迎任何帮助，谢谢你。
