Stephan Ewen commented on FLINK-1407:
-------------------------------------
Does it make sense to:
- disable logging for classes that only log exceptions (without reacting),
like the ExecutionEnvironment?
- enable logging for critical classes that react to exceptions (like
runtime.executiongraph.*) ?
> Enable log output (error level) for test cases

> In case of errors (especially flakey test cases) which most often appear on
> Travis, it would be helpful to log the error messages in order to detect the
> actual problem. Since we also have test exceptions which would be logged the
> same way and we don't want to clutter the logs, we would have to set up the
> logging for the individual classes selectively.
> What do you think?
