Jean-Christophe Petkovich created ARROW-4559:
------------------------------------------------
Summary: pyarrow can't read/write filenames with special characters
Key: ARROW-4559
URL: https://issues.apache.org/jira/browse/ARROW-4559
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.12.0
Environment: $ python3 --version
Python 3.6.6
$ pip3 freeze | grep -Ei 'pyarrow|pandas'
pandas==0.24.1
pyarrow==0.12.0
Reporter: Jean-Christophe Petkovich
When writing or reading files to or from paths that have special characters in
them, (e.g., "#"), pyarrow returns an error:
{code:python}
OSError: Passed non-file path...
{code}
This is a consequence of the following line:
https://github.com/apache/arrow/blob/master/python/pyarrow/filesystem.py#L416
File-paths will be parsed as URIs, which will give strange results for
filepaths like: "bad # actor.parquet":
ParseResult(scheme='', netloc='', path='/tmp/bad ', params='', query='',
fragment='actor.parquet')
This is trivial to reproduce with the following code which uses the
`pd.to_parquet` and `pd.read_parquet` interfaces:
{code:python}
import pandas as pd
x = pd.DataFrame({"a": [1,2,3]})
x.to_parquet("bad # actor.parquet")
x.read_parquet("bad # actor.parquet")
{code}
