I don't know the exact history of this in Arrow, but my assumption is this raises because pandas requires signed integer codes for its categorical values, as the sentinel -1 is used to denote missing values. So it seems possible to support, but would likely not preserve the unsigned nature and in some cases may require an upcast of the index type to avoid overflows -- This is an automated message from the Apache Git Service.
