When you run those commands you are not submitting the topology to a Storm cluster. You are running the topology in local mode, where Storm simulates a cluster by running the supervisors, workers and Nimbus in a single JVM. In your case this JVM is started by Maven. As a result the topology.worker.childopts setting has no effect, because there are no child processes to pass parameters to, since the workers are just running as threads in the single JVM. Normally when you submit a topology to a distributed mode Storm cluster and a supervisor process decides to start workers, those workers run in their own JVMs.
If you want to set JVM options for the local mode cluster, you should look up how to set xmx for Maven when using java:exec. Here's a stackoverflow thread about it https://stackoverflow.com/questions/21468425/mvn-javaexec- with-increased-memory. I don't understand what you are referring to when you say the result file is 50KB.
