Not able to store int or boolean from Pig to Parquet

I have a simple Pig schema that contains long and boolean properties. When trying to store the records using `parquet.pig.ParquetStorer();` I get the following error:
```
java.io.IOException: parquet.io.ParquetEncodingException: can not write value at 9 in tuple (...) from type 'likeCount: long' to type 'optional int64 likeCount'
```

首先，使用报告的 Pig schema 复现该故障，该 schema 包含 long 和 boolean 属性以及 ParquetStorer。跟踪从 Pig 元组值到报告的可选 int64 Parquet 字段的转换过程，同时也考虑 boolean 路径。只要记录能够成功存储且不再出现报告的 ParquetEncodingException，即视为完成。
