I solved this problem by just providing the config in code:

config.put(Config.TOPOLOGY_WORKER_CHILDOPTS, SOME_OPTS);

I tried to provide a topology-specific storm.yaml but it doesn't work. Correct me if you make it work to use a storm.yaml.

Update:
For anyone who wants to know what SOME_OPTS is, this is from Satish Duggana on the Storm mailing list:

Config.TOPOLOGY_WORKER_CHILDOPTS: Options which can override WORKER_CHILDOPTS for a topology. You can configure any java options like memory, gc etc

In your case it can be

config.put(Config.TOPOLOGY_WORKER_CHILDOPTS, "-Xmx1g");
