Playframework 运行Spark'时发生ClassNotFoundException；任务'；在客户主程序中编程

我正在尝试将Spark与正在运行的web UI集成。其思想是访问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返回到UI

该集群以分布式模式运行，功能齐全，并具有以下设置Hadoop 2.6和Spark 1.5.1。 提交的作业如下：

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

产生预期的结果，不引起任何问题

作为Spark/Play集成的一部分，定义了一个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，build.sbt中添加了以下代码

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

此测试的执行失败，下面是堆栈跟踪

欢迎提供任何帮助，提前谢谢
