Apache zookeeper 在Fabric8上部署ZooKeeper时出错

我试图在Fabric8中运行预打包的ZooKeeper。将创建三个实例并将其链接为一个集合。但是，当我从podsui打开其中一个日志时，我看到如下错误。有人知道怎么修理吗

• 确保所有节点都通过主机名（而不是IP）了解其他节点 通过更新每个节点上的本地DNS或

  主机

  文件

或

• 更改ZooKeeper配置（

  zoo.cfg

  ）以使用IP地址而不是 节点主机名

ZooKeeper尝试解析主机名，但无法解析，因此出现错误

Failed to resolve address: zookeeper-3
...
Failed to resolve address: zookeeper-1

Zookeeper最初尝试连接到所有可访问的实例，然后尝试进行领导人选举。您的实例似乎都无法访问

您可能忘了更新

zoo.cfg

文件中的条目。下面是默认的zoo.cfg的样子

tickTime=2000
dataDir=/var/lib/zookeeper/
clientPort=2181
initLimit=5
syncLimit=2
server.1=zoo1:2888:3888
server.2=zoo2:2888:3888
server.3=zoo3:2888:3888 

---

您需要使用合适的主机名或解析为唯一主机名的IP更新zoo1、zoo2、zoo3

您还可以发布zoo.cfg文件吗。
