  17. def scan[U >: T](z: U)(f: (U, U) ⇒ U)(implicit arg0: ClassTag[U]): RDD[U]

    Parallel prefix scan.

    Parallel prefix scan. Analogous to scan on scala sequences.

    z

    The zero element to use for initializing scan (sub)sequences. This element may be used as the initial value at multiple parallel scan subsequences.

    f

    The scanning function. Maps the latest result of scan, plus a next element, to the next prefix.

    returns

    A new RDD containing the parallel prefix scan of the input elements

  18. def scanLeft[U](z: U)(f: (U, T) ⇒ U)(implicit arg0: ClassTag[U]): RDD[U]

    Sequential-only prefix scan.

    Sequential-only prefix scan. Analogous to scanLeft on scala sequences

    z

    The zero element for initalizing the sequential prefix scan

    f

    maps the latest prefix scan value, plus a next element, to the next prefix scan value

    returns

    A new RDD containing the sequential prefix scan of the input elements.
