    Description

      Performing a limit and then an aggregate seems to generate NPE vulnerable code.

      Simple example here

      case class ABCD ( a: Int, b:Int , c:Int, d: Option[Int])
val ds = sc.parallelize(1 to 50).map( i => ABCD(i, i, i, if (i%2==0) None else Some(i))).toDS
ds.limit(5).distinct.show
