xref #37715
@jbrockmendel any idea why I am failing these tests?  Thanks for your time. Best guess is the CI started using a newer version of pyarrow and ran into #44231, so its unrelated to this PR and you can ignore those particular failures for now can you merge master @jreback Sorry I pulled from master then pushed. I guess that was the wrong thing to do. I should  have git merge.  Not sure how to undo this. So I just closed the pull request.
