> We only push Spark configuration and RSC configuration to Spark while launch
> Spark cluster now, for Spark on YARN mode, Spark need extra YARN
> configuration to launch Spark cluster. Besides this, to support dynamically
> configuration setting for RSC configuration/YARN configuration, we need to
> recreate SparkSession while RSC configuration/YARN configuration update as
> well, as they may influence the Spark cluster deployment as well.
