我正在尝试使用以下spark submit命令运行jar文件：

spark-submit --master yarn --deploy-mode cluster --executor-memory 3g --class my.package.Main my-jar-file.jar

main类是jar的主类，下面是内容（全部在scala中）：

object Main{
    def main(args: Array[String]){
        val server = HttpServer.create(new InetSocketAddress("master", 8000), 0)
        val backend = new MainProcess()
        val handlerRoot = new RootHandler()
        handlerRoot.initProcess(backend)
        server.createContext("/", handlerRoot)
        server.setExecutor(null)
        server.start()
        println("Server is started at " + server.getAddress().getHostString() + ":" + server.getAddress().getPort())
    }
}

类mainprocess是我使用从hdfs获得的文件来处理spark和spark graphx库的类。以下是我在mainprocess类中配置sparkcontext的方法：

class MainProcess{
    val config = new SparkConf()
    config.setAppName("Final GraphX App - Main")
    val sc = new SparkContext(config)
   ...
}

应用程序似乎运行正常，最终状态返回成功，但应用程序只是关闭，而不是连续运行，因为它应该是一个正在运行的服务器。我只能打开链接master:8000 once 当我尝试刷新页面时，它又回到无法连接的状态。以下是运行应用程序的日志：

这个应用程序基本上是一个使用JavaHTTPServer（com.sun.net.httpserver.httpserver）制作的web应用程序，它使用spark来处理大数据。处理程序类接受发送的请求，并创建一个新线程在后台运行spark作业。用户可以发送另一个请求来检查spark作业是否完成，这样就可以将完成的结果显示在web页面上。问题是，每当spark声称完成了一个作业（但在本例中，失败了一个作业）时，服务器都会被“杀死”。我使用的是为hadoop2.7和hadoop2.7.1构建的spark2.2.0。所有数据文件都在hdfs中。
