Not sure we should include this line into the doc. It's only needed if someone starts Redis with a generated CA certificate. And in that case if they submit an app to spark cluster, they will need to configure java options in spark specific way, i.e. using spark.executor.extraJavaOptions and spark.driver.extraJavaOptions (https://spark.apache.org/docs/latest/configuration.html). Maybe we should create a separate doc page describing it since it's more advanced topic (not for a getting-started page). What do you think?
