> {{ExprNodeDescUtils.getExprNodeColumnDesc}} extracts the
> {{ExprNodeColumnDesc}} (column descriptors) from an expression. In fact, it
> creates a map from hash to the object itself. If same hash value is generated
> for two different objects, this will result in a clash in the map and some
> expressions not being part of its values.
