How to submit a topology in storm production cluster using IDE

问题

I am facing an issue Must submit topologies using the 'storm' client script so that StormSubmitter knows which jar to upload while submitting a topology to a production cluster using IDE, while the same thing if i perform in command line using storm jar command, its running like heaven. I have seen examples of the same from githublink.

For submitting topology i am using these set of lines

conf.put(Config.NIMBUS_HOST, NIMBUS_NODE);
conf.put(Config.NIMBUS_THRIFT_PORT,6627);
conf.put(Config.STORM_ZOOKEEPER_PORT,2181);
conf.put(Config.STORM_ZOOKEEPER_SERVERS,ZOOKEEPER_ID);
conf.setNumWorkers(20);
conf.setMaxSpoutPending(5000);
StormSubmitter submitter = new StormSubmitter();
submitter.submitTopology("test", conf, builder.createTopology());

Please suggest me if this is the correct approach to run?

回答1:

Well found the solution. When we ran "storm jar" it trigger a property flag for storm.jar in the submitted jar. So if we want to programmatically submit a jar then simply set the flag this way

System.setProperty("storm.jar", <path-to-jar>);

For example:

System.setProperty("storm.jar", "/Users/programming/apache-storm-1.0.1/lib/storm-core-1.0.1.jar");
StormSubmitter.submitTopology("myTopology", config, builder.createTopology());

For submitting a topology to remote Storm cluster, you need to upload that jar to nimbus machine and then submit that jar to Cluster using NimbusClient.
You can do it like this:

Map storm_conf = Utils.readStormConfig();
storm_conf.put("nimbus.host", "<Nimbus Machine IP>");
Client client = NimbusClient.getConfiguredClient(storm_conf)
                                .getClient();
String inputJar = "C:\\workspace\\TestStormRunner\\target\\TestStormRunner-0.0.1-SNAPSHOT-jar-with-dependencies.jar";
NimbusClient nimbus = new NimbusClient(storm_conf, "<Nimbus Machine IP>",
                                <Nimbus Machine Port>);
 // upload topology jar to Cluster using StormSubmitter
String uploadedJarLocation = StormSubmitter.submitJar(storm_conf,
                                inputJar);

String jsonConf = JSONValue.toJSONString(storm_conf);
nimbus.getClient().submitTopology("testtopology",
                      <uploadedJarLocation>, jsonConf, builder.createTopology());

Here is the working example : Submitting a topology to Remote Storm Cluster

I didn't run java code for submitting myself, but I checked storm command - and it's a python file, which runs java and http://nathanmarz.github.com/storm/doc/backtype/storm/StormSubmitter.html class

The only thing I think you should worry about - is to include all needed libraries, when executing it.

I have resolved this this problem based on @abhi and @Nishu Tayal's answers, I'd like to post my code here:

public static void submitLocalTopologyWay1(String topologyName, Config topologyConf, 
        StormTopology topology, String localJar) {
    try {
        //get default storm config
        Map defaultStormConf = Utils.readStormConfig();
        defaultStormConf.putAll(topologyConf);

        //set JAR
        System.setProperty("storm.jar",localJar);

        //submit topology
        StormSubmitter.submitTopology(topologyName, defaultStormConf, topology);

    } catch (Exception e) {
        String errorMsg = "can't deploy topology " + topologyName + ", " + e.getMessage();
        System.out.println(errorMsg);
        e.printStackTrace();
    } 
}

public static void submitLocalTopologyWay2(String topologyName, Config topologyConf, 
        StormTopology topology, String localJar) {
    try {
        //get nimbus client
        Map defaultStormConf = Utils.readStormConfig();
        defaultStormConf.putAll(topologyConf);
        Client client = NimbusClient.getConfiguredClient(defaultStormConf).getClient();

        //upload JAR
        String remoteJar = StormSubmitter.submitJar(defaultStormConf, localJar);

        //submit topology
        client.submitTopology(topologyName, remoteJar, JSONValue.toJSONString(topologyConf), topology);

    } catch (Exception e) {
        String errorMsg = "can't deploy topology " + topologyName + ", " + e.getMessage();
        System.out.println(errorMsg);
        e.printStackTrace();
    } 
}

then here is a test, and you must build your code to a JAR file first.

public void testSubmitTopologySubmitLocalTopologyWay1() {   
    Config config = new Config();
    config.put(Config.NIMBUS_HOST,"9.119.84.179");   
    config.put(Config.NIMBUS_THRIFT_PORT, 6627);
    config.put(Config.STORM_ZOOKEEPER_SERVERS, Arrays.asList("9.119.84.177","9.119.84.178","9.119.84.176")); 
    config.put(Config.STORM_ZOOKEEPER_PORT,2181);

    config.put(Config.TOPOLOGY_WORKERS, 3);

    RemoteSubmitter.submitLocalTopologyWay1("word-count-test-1", config, 
            WordCountTopology.buildTopology(), // your topology
            "C:\\MyWorkspace\\project\\storm-sample-0.0.1-SNAPSHOT-jar-with-dependencies.jar");//the JAR file
}
