关注的重点应该是responseBody={error_code=15,coordinator={node_id=-1,host=,port=-1}})，在客户端进行消费之前会为ConsumerGroup向Kafka集群申请coordinater节点。kafka集群在配置或分配coordinater节点的时候可能会短暂的报这个错误。可是我的是一直出现这个错误，开始怀疑是kafka配置出现问题，后来将zookeeper上kafka的配置完全删掉再重启Kafka，再运行还是这样，后来我发现是集群上的kafka集群版本降到0.9了，而我本地的是0.10，线上环境不支持我的高版本所致。ε=(´ο｀*)))唉，早该想到是版本问题的。
