> CTAS queries fail when there is a uniontype in source table andÂ
> hive.vectorized.use.vector.serde.deserialize=false.
> ObjectInspectorUtils.copyToStandardObject in ROW_DESERIALIZE path extracts
> the value from union type. However, VectorAssignRow expects a StandardUnion
> object causing ClassCastException for any CTAS query.
