Len Frodgers commented on SPARK-13740:
--------------------------------------
Thanks for the fix, but IMO the error message is so poor as to render this fix
worse than the original behaviour.
Error: "This field is not nullable, but got None" -- but what is the field?!
In a dataframe with many non-nullable fields, it is a nightmare trying to hunt
down which field is null, since one has to resort to basic (and very slow)
trial and error.
I will happily create a PR to fix this.
Let me know if I should create a new issue for this.
