[jira] [Created] (SPARK-19871) Improve error message in verify_type to indicate which field the error is for

------------------------------------

             Summary: Improve error message in verify_type to indicate which field the error is for
                 Key: SPARK-19871
                 URL: https://issues.apache.org/jira/browse/SPARK-19871
             Project: Spark
          Issue Type: Bug
          Components: PySpark, SQL
    Affects Versions: 2.1.0, 2.0.2
            Reporter: Len Frodgers


The error message for _verify_type is too vague. It should specify for which field the type verification failed.

e.g. 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 have happily created a PR to fix this.
