⚠️ Ticket has not been started in JIRA, please click 'Start Progress'.

The CI failure seems to be a failure with failing to download python 3.1 (https://discuss.python.org/t/disappearing-macos-packages-on-python-org/11737), which is unrelated to this PR.

The failures seem to be due to conda having a bad time:

UserAgent: aws-sdk-cpp/1.8.74/S3/Linux/5.11.0-1020-azure x86_64 GCC/7.5.0
Error: mkdir /tmp/s3fs-test-4m9eos07/bucket/somefile/: file exists (*fs.PathError)
       4: cmd/api-errors.go:2082:cmd.toAPIErrorCode()
       3: cmd/api-errors.go:2107:cmd.toAPIError()

       1: net/http/server.go:2046:http.HandlerFunc.ServeHTTP()

Don't think it's related to me. I'll try rebasing in a couple days and maybe the checks will pass.

@bkietz did you want to look over this one more time? Otherwise I think we can merge.

C++ exception with description "IOError: Failed to open local file '/arrow/cpp/submodules/parquet-testing/data/delta_byte_array.parquet'. Detail: [errno 2] No such file or directory" thrown in the test body.

These failures don't appear to be me.

Hmm, it seems this PR modifies the parquet-testing submodule - perhaps it needs to be rebased/something happened during the last rebase?

Yeah that seems like what happened. I guess I still need some practice with rebasing 😅 I went with the nuclear option and squashed my commits and removed the change to the testing directory, so hopefully it'll be good now.

Ok, looks like these last two failures/timeouts are not related. Thanks for the updates!
