Description

Verifying the macOS wheels using LANG=C dev/release/verify-release-candidate.sh wheels 2.0.0 2 fails for me with

    @pytest.mark.s3
    def test_s3_real_aws():
        # Exercise connection code with an AWS-backed S3 bucket.
        # This is a minimal integration check for ARROW-9261 and similar issues.
        from pyarrow.fs import S3FileSystem
        fs = S3FileSystem(anonymous=True)
>       assert fs.region == 'us-east-1'  # default region
E       AssertionError: assert 'eu-central-1' == 'us-east-1'
E         - us-east-1
E         + eu-central-1
