Luke Hutchison commented on FLINK-6016:
---------------------------------------
Mikhail: correct, this can't be fixed easily once the lines are already split.
It needs to be fixed in the input reader state machine that does the splitting
in the first place (this is single threaded code, of necessity).
> Newlines should be valid in quoted strings in CSV

> Key: FLINK-6016
> URL: https://issues.apache.org/jira/browse/FLINK-6016
> Project: Flink
> Issue Type: Bug
> Components: Batch Connectors and Input/Output Formats
> Affects Versions: 1.2.0
> Reporter: Luke Hutchison
>
> The RFC for the CSV format specifies that newlines are valid in quoted
> strings in CSV:
> https://tools.ietf.org/html/rfc4180
> However, when parsing a CSV file with Flink containing a newline, such as:
> {noformat}
> "3
> 4",5
> {noformat}
> you get this exception:
> {noformat}
> Line could not be parsed: '"3'
> ParserError UNTERMINATED_QUOTED_STRING
> Expect field types: class java.lang.String, class java.lang.String
> {noformat}
