Yeah, the exception type varies per run. Sometimes Access Violation and
Parquet Status Exception the other. I'm also confused about that.
```(C++)
int main() {
auto reader = parquet::ParquetFileReader::OpenFile("D:\\sample.parquet",
false);
std::cout << reader->metadata()->schema()->ToString() << std::endl;
auto rg_reader = reader->RowGroup(0);
for (int i = 0; i < rg_reader->metadata()->num_columns(); i++) {
std::cout << "Column " << i << std::endl <<
rg_reader->Column(i)->descr()->ToString() << std::endl << std::endl;
}
auto column_reader =
static_cast<parquet::FixedLenByteArrayReader*>(rg_reader->Column(10).get());
int64_t bytes_read = 0;
int16_t def_levels, rep_levels;
while (column_reader->HasNext()) {
parquet::FixedLenByteArray fl_byte_array;
column_reader->ReadBatch(1, &def_levels, &rep_levels,
&fl_byte_array, &bytes_read);
break;
}
return 0;
}
```
