--------------------------------------------------------
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 change 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.
