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

             Summary: Improve JDBCOutputFormat ClassCastException
                 Key: FLINK-12204
                 URL: https://issues.apache.org/jira/browse/FLINK-12204
             Project: Flink
          Issue Type: Task
          Components: Connectors / JDBC
    Affects Versions: 1.8.0
            Reporter: Fabian Hueske
             Fix For: 1.9.0, 1.8.1


ClassCastExceptions thrown by JDBCOutputFormat are not very helpful because they do not provide information for which input field the cast failed.

We should catch the exception and enrich it with information about the affected field to make it more useful.
