>                 Key: ARROW-15910
>                 URL: https://issues.apache.org/jira/browse/ARROW-15910
>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: Parquet, Python
>    Affects Versions: 6.0.1
>         Environment: GCP JupyterLab notebooks
>            Reporter: Callista Rogers
>            Priority: Major

> running below results in {{"GetFileIno() yielded path 'myBucket/features/MyParquet.parquet/year=2022/part-0019.snappy.parquet' which is outside base dir 'gs://myBucket/features/MyParquet.parquet/' "}}
> {{import pyarrow.parquet as pq}}
> {{import gcsfs}}
> {{file_path="gs://myBucket/features/MyParquet.parquet/"}}
> {{fs=gcsfs.GCSFileSystem()}}
> {{table=pq.read_table(file_path,filesystem=fs)}}
>  
> Removing the gs:// from file_path results in a {{FileNotFoundError}}. Any variation of / or // at the beginning of the path gives me the 'outside base dir' error.
> I also ran the below and got valid results using both file_path patterns, so I know it finds the path just fine.
> {{from pyarrow.fs import FileSelector, PyFileSystem, FSSpecHandler}}
> {{filesys = PyFileSystem(FSSpecHandler(fs))}}
> {{selector = FileSelector(file_path, recursive=True)}}
> {{filesys.get_file_info(selector)}}
