提交拓扑时Apache Storm InvalidTopologyException

Question

我在提交风暴拓扑时遇到了invlaidtopologyexception。 这是代码：

TopologyBuilder topologyBuilder = new TopologyBuilder();
topologyBuilder.setSpout("konnect_smstags_spout",new Konnect_SMSTags_Spout(zkConnString,topic).getKonnectSMSTagsSpout());
topologyBuilder.setBolt("smstag_logger_bolt", new SMSTag_Logger_Bolt(),5).shuffleGrouping("konnect_smstags_spout");
topologyBuilder.setBolt("smstag_basicsummary_bolt", new SMSTag_BasicSummary_Bolt(),1).globalGrouping("smstag_logger_bolt");

这有什么问题？
