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 11 new columns ({'ArrDelay', 'Year', 'Cancelled', 'Origin', 'Reporting_Airline', 'Dest', 'Month', 'DestState', 'DepDelay', 'Flights', 'Distance'}) and 39 missing columns ({'1987', '1999', '1988', '2009', 'Total', '1992', '2010', '1993', '1996', '2011', 'Region', 'Country', '2004', '1991', '2000', '2007', '2001', 'DevName', '1989', '2003', '1997', '1983', '1990', '1980', '1981', '1995', '2006', '2012', '2013', '1998', '2002', '2005', '1984', '1985', 'Continent', '1986', '1982', '1994', '2008'}).

This happened while the csv dataset builder was generating data using
