我在Java上使用Apache Beam。我正在尝试使用本地模式在预先部署的Spark env上使用SparkRunner读取csv文件并将其写入拼花格式。DirectRunner一切正常，但是SparkRunner无法正常工作。我正在使用Maven Shade插件构建胖子。

代码如下：

Java：

public class ImportCSVToParquet{
-- ommitted
                File csv = new File(filePath);
                PCollection<String> vals = pipeline.apply(TextIO.read().from(filePath));

                String parquetFilename = csv.getName().replaceFirst("csv", "parquet");
                String outputLocation = FolderConventions.getRawFilePath(confETL.getHdfsRoot(), parquetFilename);

                PCollection<GenericRecord> processed = vals.apply(ParDo.of(new ProcessFiles.GenericRecordFromCsvFn()))
                        .setCoder(AvroCoder.of(new Config().getTransactionSchema()));

                LOG.info("Processed file will be written to: " + outputLocation);
                processed.apply(FileIO.<GenericRecord>write().via(ParquetIO.sink(conf.getTransactionSchema())).to(outputLocation));


        pipeline.run().waitUntilFinish();


}
