             Summary: [Python] Filesystem S3 tests not independent (native s3 influences s3fs)
                 Key: ARROW-10558
                 URL: https://issues.apache.org/jira/browse/ARROW-10558
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
            Reporter: Joris Van den Bossche


The filesystem tests in {{test_fs.py}} that are parametrized with all the tested filesystems have some "state" shared between them, at least in the case of S3. 

When first a test is run with our own S3FileSystem, which eg creates a directory, this directory is still present when we test the s3fs wrapped filesystem, which causes some tests to pass that would otherwise fail if run in isolation.
