As you noted, there is only one process when you run Storm in local mode. The childopts are only used in cluster mode when new JVMs are spawned (e.g. supervisor spawning workers). If you need to modify the JVM settings for a local mode cluster, you can just set the JVM settings for the process you are starting the LocalCluster from. How you do it will depend on how you build and run your project.
