-----------------------------------

             Summary: Improve error message when JDBC driver not found
                 Key: DRILL-3958
                 URL: https://issues.apache.org/jira/browse/DRILL-3958
             Project: Apache Drill
          Issue Type: Improvement
          Components: Client - HTTP
    Affects Versions: 1.2.0
            Reporter: Uwe Geercken
            Priority: Minor


When setting up a storage definition for JDBC in the Drill web UI, the appropriate driver has to be available in the 3rdparty folder before defining the storage, otherwise an error is displayed.

The error message refers to a JSON mapping error which is completely inappropriate in this case, because the error is the missing JDBC driver in the 3rdparty folder and not the JSON mapping.

I request to change the error message to something appropriate that the class/driver referred to could not be found (like for example: com.mysql.jdbc.Driver)
