-------------------------------------
Summary: [Python] Make parquet _metadata file accessible from
ParquetDataset
Key: ARROW-2763
URL: https://issues.apache.org/jira/browse/ARROW-2763
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Robert Gruener
Currently when creating a ParquetDataset it gives you access to the
_common_metadata file but not the _metadata file.
We access the metadata file to get row group information of the dataset without
opening each footer.
