--------------------------------
Summary: [C++] write_dataset with delete_matching occasionally
fails with "Path does not exist"
Key: ARROW-15285
URL: https://issues.apache.org/jira/browse/ARROW-15285
Project: Apache Arrow
Issue Type: Improvement
Components: C++
Reporter: David Li
The reproducer in ARROW-15265, once the bug there is fixed, now occasionally
fails with this:
{noformat}
Traceback (most recent call last):

raise IOError(message)
OSError: Path does not exist 'my-bucket/test8.parquet/col1=c' {noformat}
The path is different each time it fails (i.e. it's not deterministic). This is
relatively rare (2 out of 100 runs when I checked just now)
