Github user sunjincheng121 commented on the issue: https://github.com/apache/flink/pull/5218 @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
