>
> For queries that involve '*' (star) in the SELECT list, the Drill plan has
> to perform special handling of such columns since it must distinguish columns
> coming from both sides of a join. Recent planner enhancements add prefixes
> at the appropriate intermediate Project nodes and remove it at the top level
> Project.
> The Project execution operator must be enhanced in order to correctly process
> such 'annotated' Project expressions that are handed by the plan. This issue
> tracks this enhancement.
