[jira] [Created] (ARROW-12675) [C++] CSV should include line/row numbers in parsing error messages

Nate Clark created ARROW-12675:
----------------------------------

             Summary: [C++] CSV should include line/row numbers in parsing error messages
                 Key: ARROW-12675
                 URL: https://issues.apache.org/jira/browse/ARROW-12675
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Nate Clark


Currently if an error occurs while parsing a CSV file the absolute line/row number is not part of the error message. Without the line number it can be very hard to determine where the incorrect value is especially in vary large files.

It would be good if the reader and parser could keep track of the row number and maybe line number when new lines are allowed in values so that they can be included in error message.
