---------------------------------------
Yes, this looks like the same bug. Thanks.
> "Row too short" when reading CSV line with empty last field (i.e. ending in
> comma)
> ----------------------------------------------------------------------------------

> Key: FLINK-6015
> URL: https://issues.apache.org/jira/browse/FLINK-6015
> Project: Flink
> Issue Type: Bug
> Components: Batch Connectors and Input/Output Formats
> Affects Versions: 1.2.0
> Environment: Linux
> Reporter: Luke Hutchison
>
> When using env.readCsvFile(filename), if a line in the CSV file has an empty
> last field, the line ends with a comma. This triggers an exception in
> GenericCsvInput.parseRecord():
> // check valid start position
> if (startPos >= limit) {
> if (lenient) {
> return false;
> } else {
> throw new ParseException("Row too
> short: " + new String(bytes, offset, numBytes));
> }
> }
> Setting the parser to lenient would cause the last field to be left as null,
> rather than setting its value to "".
> The parser should accept empty values for the last field on a row.
