>                 URL: https://issues.apache.org/jira/browse/FLINK-4909
>             Project: Flink
>          Issue Type: Improvement
>          Components: Batch Connectors and Input/Output Formats
>    Affects Versions: 1.1.1
>            Reporter: Stefano Bortoli
>            Priority: Minor
>
> When setting the type settings for the JDBC Input Format one can easily make errors in setting the correct type (e.g. INT vs DECIMAL, or LONG vs BIG_DECIMAL)
> it would be nice to have the class cast Exception to return also the name of field causing the exception. In a sense, improve the exception message. 
> For example: java.lang.ClassCastException: java.math.BigDecimal cannot be cast to java.lang.String *for field MY_BIGDECIMAL_FIELD*
