Hyukjin Kwon resolved SPARK-21355.
----------------------------------
Resolution: Invalid
I am resolving this per https://stackoverflow.com/a/42073.

This is of course correct, but I'd like to add the reason for having to do
this: the JSON spec at ietf.org/rfc/rfc4627.txt contains this sentence in
section 2.5: "All Unicode characters may be placed within the quotation marks
except for the characters that must be escaped: quotation mark, reverse
solidus, and the control characters (U+0000 through U+001F)." Since a newline
is a control character, it must be escaped.

> JSON datasource failed to parse a value having newline in its value

> Key: SPARK-21355
> URL: https://issues.apache.org/jira/browse/SPARK-21355
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Hyukjin Kwon
> Priority: Minor
>
> I guess this is a rather corner case. I found this during testing SPARK-21289.
> It looks a bug in Jackson.
> The codes below failed to parse newline in the value.
> {code}
> scala> spark.read.json(Seq("{ \"f\": \"a\nb\"}", "{ \"f\":
> \"abc\"}").toDS).show()
> +---------------+----+
> |_corrupt_record| f|
> +---------------+----+
> | { "f": "a
> b"}|null|
> | null| abc|
> +---------------+----+
> {code}
> Meaning this also does not work
> with the JSON files as below:
> {code}
> {"f": "
> d", "f0": 3}
> {code}
> {code}
> scala> spark.read.option("multiLine", true).json("tmp.json").show()
> +--------------------+
> | _corrupt_record|
> +--------------------+
> |{"f": "
> d", "f0"...|
> +--------------------+
> {code}
> Of course, the codes below work:
> {code}
> scala> spark.read.json(Seq("{ \"f\": \"ab\"}", "{ \"f\":
> \"abc\"}").toDS).show()
> +---+
> | f|
> +---+
> | ab|
> |abc|
> +---+
> {code}
