--------------------------------------
Summary: JDBC Input format cast exception management
Key: FLINK-4909
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*
