使用动态分区将数据插入Hive表时，我遇到了问题。
我有一个普通列和一个分区列的现有表，我试图将数据插入这些列。我的代码：
// Preparing writer
WriteEntity.Builder builder = new WriteEntity.Builder();
WriteEntity entity = builder.withDatabase(DATABASE_NAME).withTable(TABLE_NAME).withPartition(null).build();
HCatWriter masterHCatWriter = DataTransferFactory.getHCatWriter(entity, CUSTOM_CONFIG);
WriterContext writerContext = masterHCatWriter.prepareWrite();
HCatWriter hCatWriter = DataTransferFactory.getHCatWriter(writerContext);
// Preparing record to be written
List<HCatRecord> hCatRecordsBatch = new ArrayList<HCatRecord>();
HCatRecord hCatRecord = new DefaultHCatRecord(2);
hCatRecord.set(0, "aaa");
hCatRecord.set(1, "bbb");
hCatRecordsBatch.add(hCatRecord);
// Writing record
hCatWriter.write(hCatRecordsBatch.iterator());
但我得到例外：
org.apache.hive.hcatalog.common.HCatException : 9001 : Exception occurred while processing HCat request : Failed while writing. Cause : org.apache.hive.hcatalog.common.HCatException : 2010 : Invalid partition values specified : Unable to configure dynamic partitioning for storage handler, mismatch between number of partition values obtained[0] and number of partition values required[1]

我浏览了hive库的代码，看起来主节点上调用的方法prepareWrite()得到错误的架构。它仅使用普通列加载模式（缺少分区列），之后，无法检索分区列的插入记录中的值（实际上在异常...number of partition values obtained[0]中表示... ）。存在同样的问题SO question但在我的情况下，我无法将列附加到架构，因为它是用prepareWrite()方法打包的。
我使用Cloudera版本5.3.2的库（它意味着Hive版本0.13.1）
我将不胜感激任何帮助。感谢。
