17. def gridGraph(sc: SparkContext, rows: Int, cols: Int): Graph[(Int, Int), Double]

    Create rows by cols grid graph with each vertex connected to its row+1 and col+1 neighbors.

    Create rows by cols grid graph with each vertex connected to its row+1 and col+1 neighbors. Vertex ids are assigned in row major order.

    sc

    the spark context in which to construct the graph

    rows

    the number of rows

    cols

    the number of columns

    returns

    A graph containing vertices with the row and column ids as their attributes and edge values as 1.0.

20. def logNormalGraph(sc: SparkContext, numVertices: Int, numEParts: Int = 0, mu: Double = 4.0, sigma: Double = 1.3, seed: Long = 1): Graph[Long, Int]

    Generate a graph whose vertex out degree distribution is log normal.

    Generate a graph whose vertex out degree distribution is log normal.

    The default values for mu and sigma are taken from the Pregel paper:

    Grzegorz Malewicz, Matthew H. Austern, Aart J.C Bik, James C. Dehnert, Ilan Horn, Naty Leiser, and Grzegorz Czajkowski. 2010. Pregel: a system for large-scale graph processing. SIGMOD '10.

    If the seed is -1 (default), a random seed is chosen. Otherwise, use the user-specified seed.

    sc

    Spark Context

    numVertices

    number of vertices in generated graph

    numEParts

    (optional) number of partitions

    mu

    (optional, default: 4.0) mean of out-degree distribution

    sigma

    (optional, default: 1.3) standard deviation of out-degree distribution

    seed

    (optional, default: -1) seed for RNGs, -1 causes a random seed to be chosen

    returns

    Graph object
