classpath of worker

[jinhong lu]

Hi, I found this about storm worker class path:

protected String getWorkerClassPath(String stormJar, Map stormConf) {
    List<String> topoClasspath = new ArrayList<>();
    Object object = stormConf.get(Config.TOPOLOGY_CLASSPATH);

    if (object instanceof List) {
        topoClasspath.addAll((List<String>) object);
    } else if (object instanceof String) {
        topoClasspath.add((String) object);
    }
    LOG.debug("topology specific classpath is {}", object);

    String classPath = Utils.workerClasspath();
    String classAddPath = Utils.addToClasspath(classPath, 
Arrays.asList(stormJar));
    return Utils.addToClasspath(classAddPath, topoClasspath);
}


According to this:
    String classAddPath = Utils.addToClasspath(classPath, 
Arrays.asList(stormJar));
user’s code will be load behind storm/lib, and storm/extlib.

Is it right?
and if I want another version of jar(for example, guava.jar), how can I do that?


Thanks,
