Looks like there are some lint failures - you can fix them locally as described at https://arrow.apache.org/docs/developers/cpp/development.html#code-style-linting-and-ci or by commenting @github-actions autotune in this PR.

I think the failures here are flukes (GHA seems to be having a bit of trouble), let's see when the Travis build finishes.

Thanks for doing this! 🙏 In the future, it can be a good idea to grep the source for the Jira issue number to see if there are any TODOs or skipped tests related to the issue. There was one in the R test suite from when the issue was originally reported; I've removed it in #10891.

Yes, I totally agree with you, thanks for the reminder.
