> {{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.
