Jun Ye edited comment on SPARK-16599 at 2/1/17 2:24 AM: -------------------------------------------------------- I got the same exception with the following code: (My Spark version is 2.1.0. Scala version: 2.11.8. Hadoop version: 2.7.3) {code} case class MyClass(id: Int, name: String) val myDF = sparkSession.sparkContext .textFile("s3a://mys3bucket/myTextFile.txt") .map(_.split("\t")) .map(_.map(_.trim)) .map(a => MyClass(a(0).toInt, a(1))) .toDF {code} The exception only happened at the following line: {code} .map(a => MyClass(a(0).toInt, a(1))) {code} If I removed this line, there is no exception. So I changed it to the following to bypass this exception. {code} val myDF = sparkSession.sparkContext .textFile("s3a://mys3bucket/myTextFile.txt") .map(_.split("\t")) .map(_.map(_.trim)) .map { case a: Array[String] => (a(0).toInt, a(1)) }.toDF("id", "name") {code} It works for me. was (Author: yetsun): I got the same exception with the following code: (My Spark version is 2.1.0.
