SparkSimulation

case class SparkSimulation(local: Boolean = false, cores: Int = 4) extends Product with Serializable

A Spark session utility wrapper.

This session can be used to parallelize simulations. It requires the local machine to have a Spark driver installed, if used with flag local = true. See the Apache Spark website https://spark.apache.org/downloads.html for installation instructions.

local

Flag to specify whether or not should run in local mode.

cores

Number of cores to use in local mode, default is 4. Set to 0 to request maximum number of cores.

  23. def parallelize[T](seq: Seq[T])(implicit arg0: ClassTag[T]): RDD[T]

    Parallelizes a sequence of type T.

    Parallelizes a sequence of type T.

    Use this to parallelize simulations and run them in a Spark session. All transformation applied to the resulting org.apache.spark.rdd.RDD are lazily executed in parallel.

    T

    Optional type parameter.

    seq

    Sequence of type T to be parallelized.

    returns

    A resilient distributed data structure org.apache.spark.rdd.RDD.

  24. def shutdown(): Unit

    Shuts down the Spark session.

    Shuts down the Spark session.

    Use this to cleanly close the Spark session and ensure all jobs are finished properly. No further sequences can be parallelized.
