如何使用Java Spark拼花写入停止JVM核心转储

Spark遇到问题，尝试“手动”创建数据集，然后将其写入parquet。我已经简化了这个例子，这样你就可以看到发生了什么

我有两个类（它们来自图书馆，所以不容易更改）

如果我从行程中除掉一些成员，它就会开始工作。如果我去掉isPrivate（）方法，它就会开始工作

---

有人知道这里发生了什么吗？

我最后不得不更改rawcinerary类定义，将isPrivate（）方法更改为与bean不同的方法。完成后，一切都正常了。可能是因为Encoders.bean无法为isPrivate创建编码器吗？我最终不得不更改RawInventurey类定义，以将isPrivate（）方法更改为与bean不同的方法。完成后，一切都正常了。可能是因为Encoders.bean无法为isPrivate创建编码器？

public class RawSearch implements Serializable {

    protected long timestamp;

    @Nullable
    protected List<RawItinerary> itineraries;

}

public class RawItinerary implements Serializable {

    protected long timestamp;

    @Nullable
    protected String originCityCode;

    @Nullable
    protected String destinationCityCode;

    protected int departDate;
    protected int returnDate;
    protected String currencyCode;

    protected double totalAmount;
    protected double totalTaxAmount;
    protected double totalSurchargeAmount;

    @Nullable
    protected String validatingCarrier;

    protected boolean multiCarrier;

    @Nullable
    protected String cabin;

    public boolean isPrivate() {
        return false;
    }

}

       List<RawSearch> searches = new ArrayList<>();

        RawSearch rawSearch = new RawSearch();

        rawSearch.setTimestamp(System.currentTimeMillis());
        rawSearch.setItineraries(new ArrayList<>());
        searches.add(rawSearch);

        RawItinerary itinerary = new RawItinerary();

        itinerary.setCabin("Coach");
        itinerary.setCurrencyCode("USD");
        itinerary.setDepartDate(20200215);
        itinerary.setDestinationCityCode("EDI");
        itinerary.setMultiCarrier(false);
        itinerary.setOriginCityCode("LON");
        itinerary.setReturnDate(0);
        itinerary.setTimestamp(System.currentTimeMillis());
        itinerary.setValidatingCarrier("BA");

        rawSearch.getItineraries().add(itinerary);

        SparkSession sparkSession = SparkSession.builder().appName("Bob").master("local[1]").getOrCreate();

        Dataset<RawSearch> searchDataset = sparkSession.createDataset(searches, Encoders.bean(RawSearch.class));

        searchDataset.write()
                .parquet("/Users/graemewallace/Downloads/bob-" + System.currentTimeMillis());

        sparkSession.close();
