The dataset generation failed because of a cast error
Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 1 new columns ({'Salary'}) and 19 missing columns ({'HmRun', 'Runs', 'RBI', 'CRBI', 'DivisionW', 'PutOuts', 'Walks', 'AtBat', 'Errors', 'Assists', 'LeagueN', 'CRuns', 'Years', 'Hits', 'CWalks', 'NewLeagueN', 'CHmRun', 'CHits', 'CAtBat'}).

This happened while the csv dataset builder was generating data using

hf://datasets/Adapting/MLO/hitters.y.csv (at revision f8cbdcb404b37b5804966dd9851064e01db9f4e6)

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)
