Storm Creating Topology

Question

I am trying to run storm starter example in Linux using Eclipse. I am getting following error and nexttuple function is never called.

ERROR:

35979 [main] INFO  o.a.s.d.supervisor - Shutting down supervisor cfba8fc6-    81e6-47cb-b8b9-ec7c700f4dfe

My topology class:

package com.storm.MobileCallLogAnalyzer;

import org.apache.storm.tuple.Fields;
import org.apache.storm.tuple.Values;

//import storm configuration packages
import org.apache.storm.Config;
import org.apache.storm.LocalCluster;
import org.apache.storm.StormSubmitter;
import org.apache.storm.topology.TopologyBuilder;

//Create main class LogAnalyserStorm submit topology.
public class LogAnalyserStorm {
   public static void main(String[] args) throws Exception{
      //Create Config instance for cluster configuration
      Config config = new Config();
      config.setDebug(true);

      //Creating Topology
      TopologyBuilder builder = new TopologyBuilder();
       builder.setSpout("call-log-reader-spout", new FakeCallLogReaderSpout());

      builder.setBolt("call-log-creator-bolt", new CallLogCreatorBolt())
         .shuffleGrouping("call-log-reader-spout");

      builder.setBolt("call-log-counter-bolt", new CallLogCounterBolt())
         .fieldsGrouping("call-log-creator-bolt", new Fields("call"));

      LocalCluster cluster = new LocalCluster();
      cluster.submitTopology("LogAnalyserStorm", config, builder.createTopology());
      Thread.sleep(10000);

      //Stop the topology
      cluster.shutdown();
   }
 }

I'm working on the virtual machine environment cloudera ( cloudera.quickstart ) so do not know if it is due to the installation of Zookeeper. Any idea?

That seems that the local storm instance is unable to connect to the embedded ZooKeeper instance, whe using local-cluster mode.

Maybe, this will help you!
