page	Minimal Configuration File

This is an example of a really minimal but complete configuration file. This one just runs one tiny instance of the SparkPi workload.

Setting spark-home and master

Spark-Bench must know the location of your Spark installation and must have master specified. You can specify these variables in your config file or in your environment

Spark variables set in config file

spark-bench = {
  spark-submit-config = [{
    spark-home = "/path/to/your/spark/installation"
    spark-args = {
      master = "XXXXXX" // replace with local, yarn, whatever
    }
    workload-suites = [
      {
        descr = "One run of SparkPi and that's it!"
        benchmark-output = "console"
        workloads = [
          {
            name = "sparkpi"
            slices = 10
          }
        ]
      }
    ]
  }]
}

Spark variables set in environment

export SPARK_HOME=/path/to/your/spark/installation
export SPARK_MASTER_HOST=XXXX # replace with local, yarn, whatever

// spark-home and master will be picked up from the environment
spark-bench = {
  spark-submit-config = [{
    workload-suites = [
      {
        descr = "One run of SparkPi and that's it!"
        benchmark-output = "console"
        workloads = [
          {
            name = "sparkpi"
            slices = 10
          }
        ]
      }
    ]
  }]
}
