I am running `bin/run-example ml.ImputerExample`. I know this will convert to something like `spark-submit --name MyApp --class MyMainClass --master local[2] myapplication.jar`. 

But what excatly it converts to? I have take a look into `bin/run-example`, but did not find the answer. The content of `bin/run-example`

```
if [ -z "${SPARK_HOME}" ]; then
  source "$(dirname "$0")"/find-spark-home
fi

export _SPARK_CMD_USAGE="Usage: ./bin/run-example [options] example-class [example args]"
exec "${SPARK_HOME}"/bin/spark-submit run-example "$@"

```
