Antoine Pitrou reassigned ARROW-7282:
-------------------------------------
Assignee: Antoine Pitrou
> [Python] let ArrowIOError subclass from FileNotFoundError when appropriate
> --------------------------------------------------------------------------
>
> Key: ARROW-7282
> URL: https://issues.apache.org/jira/browse/ARROW-7282
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.15.1
> Environment: Arch Linux, Python 3.7
> Reporter: Scott Gigante
> Assignee: Antoine Pitrou
> Priority: Minor
> Labels: exception-reporting, pyarrow
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> I get the following error when trying to open a file that does not exist.
> ```
> pyarrow.lib.ArrowIOError: Failed to open local file 'filename', error: No
> such file or directory
> ```
> In my opinion, this particular error should also subclass from Python
> FileNotFoundError. It currently only inherits from IOError (which is a
> superclass of FileNotFoundError).
> ```
> >>> import pyarrow
> >>> try:
> ... raise pyarrow.lib.ArrowIOError
> ... except IOError:
> ... pass
> ...
> >>> try:
> ... raise pyarrow.lib.ArrowIOError
> ... except FileNotFoundError:
> ... print('caught')
> ...
> Traceback (most recent call last):
> File "<stdin>", line 2, in <module>
> pyarrow.lib.ArrowIOError
> >>> try:
> ... raise pyarrow.lib.ArrowIOError
> ... except IOError:
> ... print('caught')
> ...
> caught
> ```
