Required field 'num_values' was not found in serialized data!

从报告的堆栈跟踪开始，重点检查 VectorizedParquetReader.java、ParquetFileReader 以及 Thrift DataPageHeader 的解析路径。如果可以获取受影响的 Parquet 文件，请使用它重现故障，然后确定问题出在 reader 还是序列化数据上；完成的标准是确认诊断结论，并提供一个有针对性的回归测试或书面说明。

Describe the bug, including details regarding any error messages, version, and platform.

When using iceberg, we encountered a situation where a parquet file we wrote could not be read. When reading, the following error message appeared. Judging from the exception information, it is speculated that the parquet file is damaged or has not been written properly and cannot be parsed. We have also tried a variety of parsing tools but cannot parse it normally. However, the footer of the file is normal and the schema information of the file can be obtained, but the read data cannot be parsed the DataPageHeader. parquet version is 1.13.1. Is there any tool that can restore damaged files?
