> Many vector expression classes are setting noNulls to true which does not
> work if the VRB is a scratch column being reused. The previous use may have
> set noNulls to false and the isNull array will have some rows marked as NULL.
> The result is wrong query results and sometimes NPEs (for BytesColumnVector).
> So, many vector expressions need this:
> {code:java}
> // Carefully handle NULLs...
> /*
> * For better performance on LONG/DOUBLE we don't want the conditional
> * statements inside the for loop.
> */
> outputColVector.noNulls = false;
> {code}
> And, vector expressions need to make sure the isNull array entry is set when
> outputColVector.noNulls is false.
> And, all place that assign column value need to set noNulls to false when the
> value is NULL.
> Almost all cases where noNulls is set to true are incorrect.
