@fhueske thanks for your explanation, make sense to me. I updated the PR.
The changes as follows:
- Revert the change of `RowCsvInputFormatTest.testTailingEmptyFields`.
- Unity parseField behavior when startPos = limit, except StringParser,
that is `StringParser` set error state `EMPTY_COLUMN` and set empty string to
`result`,return `limit` value as index, and other set error state
`EMPTY_COLUMN`, return `-1` as index;
Best, Jincheng
