>          Issue Type: Bug
>          Components: parquet-cpp
>         Environment: Latest parquet-cpp repository with support for compressed writes

> One issue I noticed in the file-serialize-test : building properties with the column path "schema.int64" for compression does not work (data is not getting compressed), I had to remove the "schema." prefix for it to work (even though the GroupNode is created with the "schema" prefix).
> So in parquet-cpp/src/parquet/file/file-serialize-test.cc :
> This line : WriterProperties::Builder().compression("schema.int64", codec_type)->build();
> Needs to be : WriterProperties::Builder().compression("int64", codec_type)->build();
> The test itself is not failing because it does not check that compression is actually happening, it just runs on uncompressed data every time.
