[~srowen]
let's consider the following code:
import org.apache.spark.sql.types._
val struct = StructType(StructField("f1", StringType, true) :: Nil)
val row = Row(1)
println(row.fieldIndex("f1"))
which generates the following error when executed:
Exception in thread "main" java.lang.UnsupportedOperationException: fieldIndex
on a Row without schema is undefined.
Therefore, I do not think it is taking the struct schema as param in
constructing the Row object.
