Exception in thread "main" kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING

遇到问题：

今天在启动kafka后创建topic时遇到如下错误：

[root@localhost config]# kafka-topics.sh --create --zookeeper 192.168.68.110:2181,192.168.68.111:2181,192.168.68.113:2181 --replication-factor 2 --partitions 3 --topic test

问题解决：

这是因为自己已经搭建了zookeeper集群。如果只启动单台服务器zookeeper在选举的时候将不可进行。所以zookeeper就会认为服务处于不可用状态。将node02和node03节点的zookeeper全部启动后创建topic成功
