------------------------------------
Summary: CSV Read breaks: When "multiLine" = "true", if "comment"
option is set as last line's first character
Key: SPARK-22516
URL: https://issues.apache.org/jira/browse/SPARK-22516
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.2.0
Reporter: Kumaresh C R
Try to read attached CSV file with following parse properties,
scala> *val csvFile = spark.read.option("header","true").option("inferSchema",
"true").option("parserLib", "univocity").option("comment",
"c").csv("hdfs://localhost:8020/text
CommentChar.csv"); *
csvFile: org.apache.spark.sql.DataFrame = [a: string, b: string]
scala> csvFile.show
+---+---+
| a| b|
+---+---+
+---+---+
Notice that it works fine.
If we add an option "multiLine" = "true", it fails with below exception,
scala> val csvFile =
*spark.read.option("header","true").{color:red}{color:#d04437}option("multiLine","true"){color}{color}.option("inferSchema",
"true").option("parserLib", "univocity").option("comment",
"c").csv("hdfs://localhost:8020/textCommentChar.csv");*
