我使用apachehudi将非分区表写入awss3并将其同步到hive。这是你的答案 DataSourceWriteOptions 正在使用。

val hudiOptions: Map[String, String] = Map[String, String](
      DataSourceWriteOptions.TABLE_TYPE_OPT_KEY -> "MERGE_ON_READ",
      DataSourceWriteOptions.RECORDKEY_FIELD_OPT_KEY -> "PERSON_ID",
      DataSourceWriteOptions.PARTITIONPATH_FIELD_OPT_KEY -> "",
      DataSourceWriteOptions.PRECOMBINE_FIELD_OPT_KEY -> "UPDATED_DATE",
      DataSourceWriteOptions.HIVE_PARTITION_FIELDS_OPT_KEY -> "",
      DataSourceWriteOptions.HIVE_PARTITION_EXTRACTOR_CLASS_OPT_KEY -> classOf[NonPartitionedExtractor].getName,
      DataSourceWriteOptions.HIVE_STYLE_PARTITIONING_OPT_KEY -> "true",
      DataSourceWriteOptions.KEYGENERATOR_CLASS_OPT_KEY -> "org.apache.hudi.keygen.NonpartitionedKeyGenerator"
    )

如果已分区，则成功写入表，但如果尝试写入非分区表，则会出现错误。下面是错误输出片段

这是你的密码 HoodieInputFormatUtils.getTableMetaClientForBasePath() ```
/**

• Extract HoodieTableMetaClient from a partition path(not base path).
• @param fs
• @param dataPath
• @return
• @throws IOException
  */
  public static HoodieTableMetaClient getTableMetaClientForBasePath(FileSystem fs, Path dataPath) throws IOException {
  int levels = HoodieHiveUtils.DEFAULT_LEVELS_TO_BASEPATH;
  if (HoodiePartitionMetadata.hasPartitionMetadata(fs, dataPath)) {
  HoodiePartitionMetadata metadata = new HoodiePartitionMetadata(fs, dataPath);
  metadata.readFromFS();
  levels = metadata.getPartitionDepth();
  }
  Path baseDir = HoodieHiveUtils.getNthParent(dataPath, levels);
  LOG.info("Reading hoodie metadata from path " + baseDir.toString());
  return new HoodieTableMetaClient(fs.getConf(), baseDir.toString());
  }

第283行是 `LOG.info()` 导致nullpointerexception。所以看起来为分区提供的配置值被搞乱了。此代码正在aws emr上运行。
