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'
```
