             Summary: Wrap SQL parser to avoid redundant code

                 URL: https://issues.apache.org/jira/browse/IMPALA-7915

          Issue Type: Improvement
          Components: Frontend
    Affects Versions: Impala 3.0
            Reporter: Paul Rogers
            Assignee: Paul Rogers


The FE has many repeated blocks of code to set up the lexer and parser, to parse, and to handle errors.

Move this code into a static function that can be used in place of the copies.

At the same time, provide a specific {{ParseException}} to replace the generic {{Exception}} thrown by the parser to allow easier error handling.
