nicolas paris commented on SPARK-28779:
---------------------------------------
i cannot find the lineSep option in the dataframeReader/writer csv method API.
This exists in the json method, maybe that's what you were thinking about ?

> CSV writer doesn't handle older Mac line endings
> ------------------------------------------------
>
> Key: SPARK-28779
> URL: https://issues.apache.org/jira/browse/SPARK-28779
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.3.0, 2.4.0
> Reporter: nicolas paris
> Priority: Minor
>
> The spark csv writer does not consider "\r" as a newline in string type
> columns. As a result, the resulting csv are not quoted, and they get
> corrupted.
> All \n, \r\n and \r should be considered as newline to allow robust csv
> serialization.
