Hi all,
the following code will run with Spark 2.0.2 but not with Spark 2.1.0:
//
case class Data(id: Int, param: Map[String, InnerData])
case class InnerData(name: String, value: Int)
import spark.implicits._
val e = Data(1, Map("key" -> InnerData("name", 123)))
val data = Seq(e)
val d = data.toDS()
//
Here is the exception:
Caused by: org.codehaus.commons.compiler.CompileException: File
'generated.java', Line 63, Column 46: Expression
"ExternalMapToCatalyst_value_isNull1" is not an rvalue
