[jira] [Created] (ARROW-6003) [C++] Better input validation and
error messaging in CSV reader
Neal Richardson created ARROW-6003:
--------------------------------------
Summary: [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++
Reporter: Neal Richardson
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.
