> Pandas deprecated the `MultiIndex.labels` in favor of `MultiIndex.codes`
> ([https://github.com/pandas-dev/pandas/pull/23752).] In the pandas
> parquet/feather tests, we are now seeing warnings about this (and I assume
> there will be warnings as well in pyarrow tests if running on pandas master).
