Yanwen Lin reassigned KAFKA-13032:
----------------------------------
Assignee: Yanwen Lin
> Impossible stacktrace
> ---------------------
>
> Key: KAFKA-13032
> URL: https://issues.apache.org/jira/browse/KAFKA-13032
> Project: Kafka
> Issue Type: Improvement
> Components: streams
> Affects Versions: 2.8.0
> Reporter: Niclas Hedhman
> Assignee: Yanwen Lin
> Priority: Minor
> Labels: beginner, easy-fix
>
> I am presented with a stacktrace that has not a single touch point in my
> code, so it is incredibly difficult to figure out where the problem could be.
> I think more RuntimeExceptions need to be caught and pull out information at
> each level that is providing any additional hint of where we are.
> For instance, each node could prepend its reference/name and one would have a
> chance to see where we are...
> ```
