    Description

      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.
