Description:
[StructType.findNestedField|https://github.com/apache/spark/blob/db2625c70a8c3aff64e6a9466981c8dd49a4ca51/sql/catalyst/src/main/scala/org/apache/spark/sql/types/StructType.scala#L325]
is unable to reach nested field below two directly nested maps or arrays.
Whenever it reaches a map or an array, it'll throw an `invalidFieldName`
exception if the child is not a struct.
The following throws '{{{}Field name `a`.`element`.element`.`i` is invalid:
`a`.`element`.`element` is not a struct.'{}}}, even though the access path is
valid:
{code:java}
val schema = new StructType()
.add("a", ArrayType(ArrayType(
new StructType().add("i", "int"))))
findNestedField(Seq("a", "element", "element", "i"), schema) {code}
