JVM Tuning in Local Mode

[Mitchell Rathbun (BLOOMBERG/ 731 LEX)]

I am looking to tune the JVM settings for the Storm instance that we are 
running locally. I know in cluster mode this is done for various nodes by using 
the childopts property in storm.yaml (worker.childopts, nimbus.childopts, 
etc.). What should I set for this to work in local mode? Is it necessary for 
all of these properties to be set even though there is only one process that is 
run? Or is there a simpler way to do it?
