> When a RecordReader fails for whatever reason, it would be helpful to include in the error log message, a record number to help easily identify which record failed.
> My particular use case was when using QueryRecord and ValidateRecord with CSVReader on a file which was mostly comma delimited except for one line which was pipe delimited. The error message logged did not include the line number where the parsing failed.  There was an IlegalArgumentException thrown with the message
> {code:java}
> Index for header 'id' is 1 but CSVRecord only has 1 values!
> {code}
> This made it very difficult to identify which record in the CSV file was causing the CSVReader to fail.
