Fabian Hueske commented on FLINK-841:
-------------------------------------
This message tells the user what went wrong but doesn't help how to avoid /
overcome this problem.
The error message for the original exception in this issue should tell the
user, that the delta set (or however we call it) wants to update a key that
does not exist in the solution set.
> Updating a non-existing key in solution set yields a NPE

> This NPE should be replaced by some meaningful error message.
