How to disable/turn off the logging feature from Storm

Question

I want to turn off the logging feature offered by default when we run from local cluster. Currently its logging so many information on the console.

Below is the example of log:

261 [main] INFO  backtype.storm.daemon.task  - Shut down task Getting-Started-Toplogie-1-1376388324:2
2261 [main] INFO  backtype.storm.daemon.task  - Shutting down task Getting-Started-Toplogie-1-1376388324:1
2262 [Thread-24] INFO  backtype.storm.util  - Async loop interrupted!
2276 [main] INFO  backtype.storm.daemon.task  - Shut down task Getting-Started-Toplogie-1-1376388324:1
2278 [main] INFO  backtype.storm.daemon.worker  - Terminating zmq context
2279 [main] INFO  backtype.storm.daemon.worker  - Disconnecting from storm cluster state context
2279 [main] INFO  backtype.storm.daemon.worker  - Waiting for heartbeat thread to die
2279 [Thread-27] INFO  backtype.storm.util  - Async loop interrupted!
2308 [main] INFO  backtype.storm.testing  - Shutting down in process zookeeper
2309 [main] INFO  backtype.storm.testing  - Done shutting down in process zookeeper
2309 [main] INFO  backtype.storm.testing  - Deleting temporary path /tmp/255fe7c8-1407-4f43-8771-2217905232ab

After going through many docs, I ended up with the below code, I am able to turn off the logging from within class.

static Logger logger = Logger.getLogger(TopologyMain.class);

public static void main(String[] args) throws InterruptedException, AlreadyAliveException, InvalidTopologyException {        
      logger.setLevel((Level) Level.FATAL);
      logger.debug("Here is some DEBUG");
      logger.info("Here is some INFO");
      logger.warn("Here is some WARN");
      logger.error("Here is some ERROR");
      logger.fatal("Here is some FATAL");
 }
}

Output (correct) : 0 [main] FATAL TopologyMain - Here is some FATAL

But I require to change the logging configure of storm/zookeper,etc..

Could anyone please help on this?

Update: The following is the code I tried, but it does not work. I tried with version 0.7.1, 0.8.2 & 0.9.0-wip*

        //Configuration
        Config conf = new Config();
        conf.put(Config.TOPOLOGY_DEBUG, false);  //Tried this alone
        conf.setDebug(false);  //Tried this alone & tried both together as well.. No change :-(

Storm is really chatty and tells a lot of information but if you want to silence it, you can set Config.TOPOLOGY_DEBUG to false.

When you set Config.TOPOLOGY_DEBUG to true, you are telling Storm to log a message every time a tuple is emitted from any spout or bolt.
