Nathan, could you expand on what you mean by "your data structure".
yang...@bupt.edu.cn, could you try turning off *Config.TOPOLOGY_FALL_BACK_ON_JAVA_SERIALIZATION ?**Config conf = new backtype.storm.Config();* conf.setFallBackOnJavaSerialization(false);StormSubmitter.submitTopology(topo_name, conf, builder.createTopology()); If what I think is happening is true, you will receive a different error in your worker.
