--------------------------------
Summary: The expression parser in Drill should throw exception and
stop when it sees parsing error in expr
Key: DRILL-449
URL: https://issues.apache.org/jira/browse/DRILL-449
Project: Apache Drill
Issue Type: Bug
Reporter: Jinfeng Ni
Assignee: Jinfeng Ni
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.
