>
> Today, when the expression parser in Drill parses the expression in logical /
> physical plan, and sees a parsing error, it silently issue an warning, and
> continue the execution, and leading to an invalid or partially complete plan.
> Such plan will eventually hit error during run-time execution phase.
> In stead, the parser should stop the execution immediately and raise
> exception, when it sees a parsing error in the expression. This will help
> catch the error in an early stage, and make debugging the error an easier
> task.
