> [Python][Parquet] Fix a bug when partition filters has empty result
> -------------------------------------------------------------------
>
> Key: ARROW-10706
> URL: https://issues.apache.org/jira/browse/ARROW-10706
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Reporter: Weiyang Zhao
> Priority: Major
>
> The below code will raise IndexError:
> {{dataset = pq.ParquetDataset(}}
> base_path, filesystem=fs,
> filters=[('string', '=', "notExisted")],
> use_legacy_dataset=True
> {{)}}
> when the partition 'string' does not have a matching partition value
> 'notExisted'.
> The correct behavior should be returning an empty dataset with the actual
> schema.
