Zookeeper有KeeperException但Kafka能够创建主题并生成/消费

我最近在单节点CDH 5设置上设置Kafka，目的是在移动到真实集群之前在单个节点上播放它 . 最初，我刚刚启动了zookeeper服务器，使用kafka服务器，一切都很好 . 我可以看到zookeeper在2181运行，而Kafka在9092运行 . 然后我创建了一个主题，并启动了消费者和 生产环境 者，消费者可以看到 生产环境 者发送的消息 .

幸福地在我脸上，我移动到带有zookeeper日志的标签，看到了这个：

看起来zookeeper无法找到节点 . . . 东西 . 但是，如果是这样的话，为什么我的所有命令都有效？我能够创建一个主题，然后为订阅它生成一些数据，而订阅它的消费者也获得数据？

如果有帮助，我的zookeeper版本是3.4.6，我的Kafka版本是0.8.2.1 . 哦，路径/ tmp / zookeeper存在 .
