My sampling ratio is so low that I only see the Long values of data items and infer it's a Long. When I meet the data that's actually longer than Long, I get the error I posted; basically it's the same situation as when specifying a wrong schema manually. So is there any way around this other than increasing the sample ratio to discover also the very BigDecimal-sized numbers? Thanks Tobias
