I put together a simple example of this and described it here: https://softwarematters.wordpress.com/2015/11/02/deploying-a-properties-file-with-a-storm-topology/

They will then be available to use through the stormConf map<https://github.com/apache/storm/blob/master/storm-core/src/jvm/backtype/storm/topology/IBasicBolt.java#L25> in the prepare() method of each of your bolts.

We thought that the way to do this was to add additional arguments to storm.yaml for the worker: worker.childopts: "-Xmx805306368 -Dmongodb.hosts=mongo.host -Dmongodb.ports=27017" However the topology does not appear to be picking this up. We also tried adding those arguments to the options to nimbus.childopts and supervisor.childopts. Also tried from the command line of storm: storm jar mytopo.jar my.topo.foo.bar mytopo -Dmongodb.hosts=mongo.host -Dmongodb.ports=27017 Is there a way to do this?
