> 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
> Attachments: testCommentChar.csv
>
>
> 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/test
> CommentChar.csv"); *
> csvFile: org.apache.spark.sql.DataFrame = [a: string, b: string]
>
> scala> csvFile.show
> +---+---+
> | a| b|
> +---+---+
> +---+---+
> {color:#8eb021}*Noticed that it works fine.*{color}
> If we add an option "multiLine" = "true", it fails with below exception. This happens only if we pass "comment" == input dataset's last line's first character
> 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/testCommentChar.csv");*
