Test case:

case class Data(a: Int, B: Int, n: Nested, nestedArray: Seq[Nested])
case class Nested(a: Int, B: Int)

  test("nested repeated resolution") {
    TestHive.sparkContext.parallelize(Data(1, 2, Nested(1,2), Seq(Nested(1,2))) :: Nil)
      .registerAsTable("nestedRepeatedTest")
    hql("SELECT nestedArray[0].a FROM nestedRepeatedTest").collect()
  }
