>
> Key: ARROW-16753
> URL: https://issues.apache.org/jira/browse/ARROW-16753
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 6.0.1
> Environment: Ubuntu 20.04 LTS
> Reporter: David Rauschenbach
> Priority: Major
> Labels: good-second-issue, pull-request-available
> Time Spent: 50m
> Remaining Estimate: 0h
>
> The following code to list my root directory fails:
>
> {code:java}
> FileSelector file_selector;
> file_selector.base_dir = "/";
> file_selector.allow_not_found = true;
> file_selector.recursive = true;
> auto result = fs.GetFileInfo(file_selector);{code}
> The result.ok() value returns {+}false{+}, and then result.status().message() returns {+}Cannot list directory '/var/run/wpa_supplicant'{+}.
> An examination of the /run directory (which /var/run symlinks to) shows:
>
> {code:java}
> $ ls -al /run
> drwxr-xr-x 35 root root 1040 Jun 6 06:11 .
> drwxr-xr-x 20 root root 4096 May 20 12:42 ..
> ...
> drwxr-x--- 2 root root 60 Jun 4 12:14 wpa_supplicant{code}
> And then attempting to list this directory reveals:
>
> {code:java}
> $ ls -al /run/wpa_supplicant/
> ls: cannot open directory '/run/wpa_supplicant/': Permission denied{code}
>
> As a user of LocalFileSystem, I should be able to list all of the files that I have access to.
