     *
     * new ZkHosts(brokerZkStr):brokerZkStr逗号分隔，kafka的zookeeper集群
     * topic:storm订阅的topic，即从哪个topic读取消息
     * spout会根据config的zkRoot和id两个参数在zookeeper上为每个kafka分区创建保存kafka偏移量的路径，如：/zkRoot/id/partitionId。
     * {@link PartitionManager#committedPath()}
     * zkRoot:偏移量保存的zk根路径
     * id:如果重新运行，希望获取同样的偏移量，则设置为固定的ID
     * PS：kafka新版本已经不将偏移量保存在zookeeper了。而且也不推荐将offset写入zk（低效）。
