spark ssc.textFileStream не передает файлы из каталога

Я пытаюсь выполнить приведенный ниже код, используя eclipse (с maven conf) с 2 рабочими, и каждый из них имеет 2 ядра, или также пробовал с помощью spark-submit.

public class StreamingWorkCount implements Serializable {

    public static void main(String[] args) {
        Logger.getLogger("org.apache.spark").setLevel(Level.WARN);
        JavaStreamingContext jssc = new JavaStreamingContext(
                "spark://192.168.1.19:7077", "JavaWordCount",
                new Duration(1000));
        JavaDStream<String> trainingData = jssc.textFileStream(
                "/home/bdi-user/kaushal-drive/spark/data/training").cache();
        trainingData.foreach(new Function<JavaRDD<String>, Void>() {

            public Void call(JavaRDD<String> rdd) throws Exception {
                List<String> output = rdd.collect();
                System.out.println("Sentences Collected from files " + output);
                return null;
            }
        });

        trainingData.print();
        jssc.start();
        jssc.awaitTermination();
    }
}

И журнал этого кода

Проблема в том, что я не получаю данные из файла, который находится в каталоге. Помогите пожалуйста мне.
