How to use Drools in the topology

[张博]

Hi!
Now I want to use Drools in a blot,it works normal in the LocalCluster, but
when I put it to the production cluster,it has error.
The blot:
public class DealLostBolt extends BaseRichBolt {

  private static final long serialVersionUID = 1L;

  private static final Logger LOGGER =
LoggerFactory.getLogger("DEAL_LOST_BOLT");

  private OutputCollector collector;

  private KieSession kieSession;

  private FactHandle factHandle;

  @Override
  public void execute(Tuple input) {
    // 获取数据
    String sentence = (String) input.getValue(0);
    LOGGER.info("DealLostBolt获取到的数据：" + sentence);

    // 数据转换
    PutDataPoint dataPoint = Json.fromJson(PutDataPoint.class, sentence);

    KieServices ks = KieServices.Factory.get();
    KieContainer kieContainer = ks.getKieClasspathContainer();
    kieSession = kieContainer.newKieSession("all-rule");
    kieSession.getAgenda().getAgendaGroup("deal-lost").setFocus();

    factHandle = kieSession.insert(dataPoint);
    kieSession.fireAllRules();
    kieSession.delete(factHandle);

    collector.emit(new Values(sentence));
  }

  @Override
  public void declareOutputFields(OutputFieldsDeclarer declarer) {
    declarer.declare(new Fields("value"));

  }

  @Override
  public void prepare(Map stormConf, TopologyContext context,
OutputCollector collector) {
    this.collector = collector;
  }

}
The erros:
