Question

我正在使用SparkLauncher从代码中提交spark应用程序。

        Map<String, String> env = new HashMap<String, String>();
        env.put("SPARK_PRINT_LAUNCH_COMMAND", "1");

        System.out.println("Creating SparkLauncher");
        SparkLauncher launcher = new SparkLauncher(env);
        launcher.setSparkHome(sparkHome);
        launcher.setAppResource(appResource);
        launcher.setMaster(sparkMaster);
        launcher.setMainClass(mainClass);
        launcher.setAppName("TestFromJersey")
        .setVerbose(true)
        .setConf("spark.cores.max", "20")
        .setConf("spark.executor.memory", "30G")
        .setConf("spark.executor.extraJavaOptions", "-XX:+UseG1GC -XX:+PrintFlagsFinal -XX:+PrintReferenceGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintAdaptiveSizePolicy -XX:+UnlockDiagnosticVMOptions -XX:+G1SummarizeConcMark -XX:ConcGCThreads=13 -XX:NewRatio=1 -XX:+PrintTenuringDistribution");

        for(File f : new File("/home/user/jars").listFiles()){
            launcher.addJar(f.getAbsolutePath());
        }

        try {
            System.out.println("Launching Spark Job from SparkLauncher");
            launcher.addAppArgs("--jobName myJobName",
                    "--time "+System.currentTimeMillis()+"",
                    "--authUser admin",
                    "--savePage true");
            launcher.startApplication(new SparkAppHandle.Listener() {
                   @Override public void stateChanged(SparkAppHandle h) { 
                       System.out.println("App State:" + h.getState());
                   }
                   @Override public void infoChanged(SparkAppHandle h) { } 
                  });
        } catch (IOException e) {
            // TODO Auto-generated catch block
            System.out.println("error in launching Spark Application");
            e.printStackTrace();
        }

现在，作业根本没有运行，并且没有调用处理函数，我认为这是因为作业配置错误。在输出日志中，我可以看到以下错误：

org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option: -jobName myJobName

所以，在我看来，代码无法从sparkArguments中单独识别appArgs。

任何指针？是我用于添加AppArgs正确的格式吗？

好的，通过一些命中和试验，指定参数的正确方法是：

launcher.addAppArgs("--jobName","myJobName",
                    "--authUser","admin",
                    "--savePage","true");

SparkLauncher：App args被视为无法识别的选项
