我需要将一个csv文件解析为xml并将其写入hdfs。我成功地完成了第一部分,但在写入时出现错误。以下是代码。
private static void writeToXml(String inputPath, String outputPath) throws IOException, JSchException {
Configuration configuration = new Configuration();
configuration.set("fs.defaultFS", "hdfs://nn");
FileSystem fileSystem = FileSystem.get(configuration);
Path iPath = new Path(inputPath);
Path oPath = new Path(outputPath);
FSDataInputStream inputStream = fileSystem.open(iPath);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, StandardCharsets.UTF_8));
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet("Sheet");
AtomicReference<Integer> row = new AtomicReference<>(0);
try (Stream<String> stream = bufferedReader.lines()) {
stream.forEach(line -> {
Row currentRow = sheet.createRow(row.getAndSet(row.get() + 1));
String[] nextLine = line.split(";");
Stream.iterate(0, i -> i + 1).limit(nextLine.length).forEach(i -> {
currentRow.createCell(i).setCellValue(nextLine[i]);
});
});
FSDataOutputStream outputStream = fileSystem.create(oPath);
ByteArrayOutputStream out = new ByteArrayOutputStream();
workbook.write(out);
outputStream.write(out.toByteArray());
outputStream.flush();
}
}
它会失败,并显示此错误。

在这一行。
workbook.write(out);
编辑另一个我试图写入的代码段。失败并出现相同的错误。
FSDataOutputStream outputStream = fileSystem.create(oPath);
workbook.write(outputStream);
outputStream.flush();
我做错了什么?

最后,我找不到我的依赖项有什么问题,我用下面的依赖项在spark中重写了整个过程。
请注意,xmlbeans是3. 1. 0版本。由于某种原因,更高版本对我不起作用。
另外请注意,我只需要spark-excel_2.11来本地测试它,其他的都是因为它在集群上运行时一直出现noClassDefFound而添加的。
代码最终也变得简单了很多。
