>
> Currently for certain types of RexNodes (RexOver, RexCorrelVariable)
> DrillOptiq does not convert it to the equivalent logical expressions. In that
> case we simply return a NullExpression (minor type: Null) and we error out
> later in execution when we try to allocate a vector with minor type Null. We
> should error out early in DrillOptiq that there was a planning issue
> indicating the particular RexNode that wasn't handled correctly.
