我在一个码头工人在Mac上（W /泊坞窗机）上运行的卡夫卡（0.10.0.0）。 我得出我的Dockerfile从Spotify的，这意味着卡夫卡和动物园管理员在同一图像中运行。
我的实例启动干净，打探里面似乎一切正常/ OK。
泊坞窗2181和9092端口映射到高端口，在这种情况下32822和32820。 从我跑卡夫卡泊坞窗外面，我能够成功地远程登录192.168.99.100 32822（其中192.168.99.100是我的泊坞窗机的IP）。 从那里，我可以发出一个动物园管理员命令，并得到预期的输出。
这一切似乎都那么令人鼓舞，但......我再试试这个代码：
val numPartitions = 4
val replicationFactor = 1
val topicConfig = new java.util.Properties
// zookeeper = "192.168.99.100:32822"
val zkClient = ZkUtils(zookeeper, 10000, 10000, false)
try {
AdminUtils.createTopic(zkClient, topic, numPartitions, replicationFactor, topicConfig)
} catch {
case k: kafka.common.TopicExistsException => // do nothing...topic exists
}
zkClient.close()
这会产生这个错误的输出：

它看起来像我无法连接（大概到动物园管理员）。 为什么不？
