title: Error opening a parquet file on Amazon S3 using pyarrow
body: <p>I have this code, which is supposed to read a single column data from a parquet file stored on S3:
  <code>fs = s3fs.S3FileSystem()
  data_set = pq.ParquetDataset(f"s3://{bucket}/{key}", filesystem=fs)
  column_data = data_set.read(columns=[col_name])</code></p>
  
  <p>and I get this excption:
  validate_schemas
      self.schema = self.pieces[0].get_metadata(open_file).schema
  IndexError: list index out of range</p>
  
  <p>I upgraded to the latest version of pyarrow but it did not help</p>
