无法提交简单的SnappySQLJob

Question

我无法提交只执行System.out.println（）的简单作业。这是我从SnappyData Lead返回的错误。

snappy-job.sh submit --lead 10.0.18.66:8090 --app-name SimpleJobApp
--class snappydata.jobs.SimpleJob --app-jar simpleJob.jar OKOK{   "status": "ERROR",   "result": {
    "message": "null",
    "errorClass": "scala.MatchError",
    "stack": ["spark.jobserver.JobManagerActor$$anonfun$spark$jobserver$JobManagerActor$$getJobFuture$4.apply(JobManagerActor.scala:244)", "scala.concurrent.impl.Future$PromiseCompletingRunnable.liftedTree1$1(Future.scala:24)", "scala.concurrent.impl.Future$PromiseCompletingRunnable.run(Future.scala:24)", "java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)", "java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)", "java.lang.Thread.run(Thread.java:745)"]   }

这是工作：

public class SimpleJob implements SnappySQLJob {

    /**
     * 
     */
    public SimpleJob() {
        System.out.println(getClass().getSimpleName()+" Created");
    }

    @Override
    public Object runJob(Object sparkContext, Config jobConfig) {
        SnappyContext snappyContext = (SnappyContext)sparkContext;
        System.out.println(getClass().getSimpleName()+".runJob: executed");
        return null;
    }

    @Override
    public SparkJobValidation validate(Object sparkContext, Config jobConfig) {
        SnappyContext snappyContext = (SnappyContext)sparkContext;
        System.out.println(getClass().getSimpleName()+".validate: executed");
        return null;
    }

}

使用scala API的Java程序会出现此错误。我已使用Java API编写了SimpleJob。

public class SimpleJob extends JavaSnappySQLJob {

  public SimpleJob() {
    System.out.println(getClass().getSimpleName()+" Created");
  }

  @Override
  public Object runJavaJob(SnappyContext snappyContext, Config config) {
       System.out.println(getClass().getSimpleName()+".runJob:    
       executed");
       return null;
  }

  @Override
  public JSparkJobValidation isValidJob(SnappyContext snappyContext, Config config) {
System.out.println(getClass().getSimpleName()+".validate: executed");
return new JSparkJobValid();
}

}
