------------------------------------
Summary: Spark CSV multiline with CRLF
Key: SPARK-25506
URL: https://issues.apache.org/jira/browse/SPARK-25506
Project: Spark
Issue Type: Improvement
Components: Input/Output
Affects Versions: 2.3.1, 2.2.0
Environment: spark 2.2.0 and 2.3.1
scala 2.11.8
Reporter: eugen yushin
Spark produces empty rows (or ']' when printing via call to `collect`) dealing
with '\r' character at the end of each line in CSV file. Note, no fields are
escaped in original input file.
{code:java}
val multilineDf = sparkSession.read
.format("csv")
.options(Map("header" -> "true", "inferSchema" -> "false", "escape" -> "\"",
"multiLine" -> "true"))
.load("src/test/resources/multiLineHeader.csv")
val df = sparkSession.read
.format("csv")
.options(Map("header" -> "true", "inferSchema" -> "false", "escape" -> "\""))
.load("src/test/resources/multiLineHeader.csv")
multilineDf.show()
multilineDf.collect().foreach(println)
df.show()
df.collect().foreach(println)
{code}
