> Project: ORC
> Issue Type: Improvement
> Affects Versions: 1.4.4, 1.4.5, 1.6.3, 1.6.4, 1.6.5, 1.7.0

> #ORC-629 added an extra check (part of RecordReaderImp) disabling PPD when
> DoubleColumnStats min, max or sum is a non-Finite number.
> However, the check is unnecessarily broad – the way stats are updated, using
> just sum for the check would suffice.
