-----------------------------------
Summary: [C++] S3FileSystem::Impl::IsEmptyDirectory fails on
Amazon S3
Key: ARROW-10942
URL: https://issues.apache.org/jira/browse/ARROW-10942
Project: Apache Arrow
Issue Type: Bug
Components: C++
Affects Versions: 2.0.0
Reporter: Juan Galvez
Running S3FileSystem::GetFileInfo() where the path is in the form
"s3://bucket-name/dir-name" and this is a bucket on AWS S3, it throws the
following error:
"When reading information for key 'dir-name' in bucket 'bucket-name': AWS Error
[code 15]: No response body.
I tracked down the issue to the IsEmptyDirectory method, and noticed that
removing kSep from this line:
req.SetKey(ToAwsString(key) + kSep);
fixes the issue.
However, I don't know why kSep is needed in the first place so I'm not sure
what a good solution would be.
Also, the key variable on entering IsEmptyDirectory is just the name of the
directory (doesn't have separators).
