Fabian Hueske commented on FLINK-9341:
--------------------------------------
Thanks for investigating the issue [~kgeis] and [~Sergey Nuyanzin].
I completely agree that we should improve the error message.
Would one of you mind to create a corresponding JIRA issue and maybe also be
interested in contributing the improvement?
Thanks, Fabian
