[GitHub] drill issue #1138: DRILL-4120: Allow implicit columns for Avro storage forma...

    As @arina-ielchiieva points out, this change backs out plan-time knowledge of schema. This may not affect run-time accuracy. However, it does mean that queries can be planned, based on not knowing types, that fail at runtime when types are learned. This seems more like a bug that a feature. In general, we should use all information available. It is not helpful to ignore information if doing so results in poorer user experience.
