> The {{SparkClientImpl#startDriver}} currently looks for the {{SPARK_HOME}} directory
and invokes the {{bin/spark-submit}} script, which spawns a separate process to run the Spark
application.
> {{SparkLauncher}} was added in SPARK-4924 and is a programatic way to launch Spark applications.
> I see a few advantages:
> * No need to spawn a separate process to launch a HoS --> lower startup time
> * Simplifies the code in {{SparkClientImpl}} --> easier to debug
> * {{SparkLauncher#startApplication}} returns a {{SparkAppHandle}} which contains some
useful utilities for querying the state of the Spark job
> ** It also allows the launcher to specify a list of job listeners
