Yeah but it is not going to work for me. We already have direct topology submission by calling python script from Java app. This requires to know location of the script on the nimbus machine. We are trying to avoid that.

I just created a form to upload the jar as a file upload and execute it on nimbus hosts. ./R On Thu, Feb 18, 2016 at 11:16 AM, Kazansky, Michael <[email protected]<mailto:[email protected]>> wrote: Hi Storm gurus, I am working on the project which should allow users to submit their topology jars to Storm. We successfully using command line but now I need to write application which allows user to submit jar through let say browser. Here is what I am trying to do Config conf = new Config(); TopologyBuilder topoBuilder = new TopologyBuilder(); conf.put(Config.NIMBUS_HOST, topologyModel.getHost()); conf.setDebug(true); Map stormConf = Utils.readStormConfig(); stormConf.put(Config.NIMBUS_HOST, topologyModel.getHost()); // topology submit NimbusClient nimbus = new NimbusClient(stormConf, topologyModel.getHost(), null != topologyModel.getNimbusPort() ? topologyModel.getNimbusPort() : 6627); String uploadedJarLocation = StormSubmitter.submitJar(stormConf, topologyModel.getArtifactUrl()); System.setProperty("storm.jar", uploadedJarLocation.concat(" ").concat(topologyModel.getMainClass())); String jsonConf = JSONValue.toJSONString(stormConf); //StormTopology topology = buildToplogy(topologyModel); //SubmitOptions options = new SubmitOptions(); //client.jartransformer.class nimbus.getClient().submitTopology(topologyModel.getTopologyName(), uploadedJarLocation, jsonConf, topoBuilder.createTopology()); success = true; I looked at the storm python script and saw that main class name is concatenated to JVM_OPTS That’s why I added this line System.setProperty("storm.jar", uploadedJarLocation.concat(" ").concat(topologyModel.getMainClass())); But when I execute the code in test I only see empty topology without spouts and bolts in Storm UI with only one worker and one executor. Main class in the jar has the code to submit spouts and bolts with parallelism 3 so most definitely main class wasn’t picked up. Is there any way to implement this command python ${storm_home}/bin/storm jar ${dsl_apps_dir}/dist/${jarname} $mainclass in Java besides calling it (which is already done) directly?
