> 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.
