原因分析：
查看storm官网关于kafka的文档上看到：
ZkHosts在从网上拷贝过来的代码上，使用了第一种构造方法。于是改成第二中构造，即使用默认的构造方法
ZkHosts is what you should use if you want to dynamically track Kafka broker to partition mapping. This class uses Kafka's ZooKeeper entries to track brokerHost -> partition mapping. You can instantiate an object by calling java public ZkHosts(String brokerZkStr, String brokerZkPath) public ZkHosts(String brokerZkStr) Where brokerZkStr is just ip:port (e.g. localhost:2181). brokerZkPath is the root directory under which all the topics and partition information is stored. By default this is /brokers which is what the default Kafka implementation uses.
By default, the broker-partition mapping is refreshed every 60 seconds from ZooKeeper. If you want to change it, you should set host.refreshFreqSecs to your chosen value.
但是自己却不是特别理解这个brokerZkPath路径，下来抽点时间把框架原理整整，如果有知道的大牛大神，请不吝赐教，谢谢。
解决方案：
BrokerHosts brokerHosts = new ZkHosts("wycoldb01:2181,wycoldb02:2181,wycoldb05:2181", "/kafka/brokers");
修改为：
BrokerHosts brokerHosts = new ZkHosts("wycoldb01:2181,wycoldb02:2181,wycoldb05:2181");
问题解决！
