Resolution: Fixed
> [C++] Better input validation and error messaging in CSV reader
> ---------------------------------------------------------------
>
> Key: ARROW-6003
> URL: https://issues.apache.org/jira/browse/ARROW-6003
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, R
> Reporter: Neal Richardson
> Assignee: Antoine Pitrou
> Priority: Major
> Labels: csv
> Fix For: 0.16.0
>
>
> Followup to https://issues.apache.org/jira/browse/ARROW-5747. The error
> message(s) are not great when you give bad input. For example, if I give too
> many or too few {{column_names}}, the error I get is {{Invalid: Empty CSV
> file}}. In fact, that's about the only error message I've seen from the CSV
> reader, no matter what I've thrown at it.
> It would be better if error messages were more specific so that I as a user
> might know how to fix my bad input.
