---------------------------------
Summary: Improve exception handling int Streaming runtime
Key: FLINK-1593
URL: https://issues.apache.org/jira/browse/FLINK-1593
Project: Flink
Issue Type: Improvement
Components: Streaming
Reporter: Gyula Fora
The current exception handling logic is not very helpful when trying to debug
an application. In many cases with serialization/user code or other exceptions,
the error is just logged and not propagated properly. This should mainly be
fixed in the StreamInvokables.
Some improvements that could be made:
-Serialization/Deserialiaztion and other system errors should be propagated
instead of just silently logged
-User code exceptions should be better handled, for instance I think it would
be helpful to log them to INFO so that users can instantly see it.
