Github user WeichenXu123 commented on the pull request: https://github.com/apache/spark/pull/13007#issuecomment-218037385 @HyukjinKwon I run existing test against this patch and all pass. If need I will add a new test in CSVSuit. And I think the only reason cause the bug is reading first line handling in the code. Because a row with multi-line in csv format is legal and the current csv datasource code using LIB `com.univocity.parsers.csv` also support it. Only when a data row with multi-line appear at file beginning will cause bug and I think this patch can fix it easily.
