Exception in thread "main" kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out wait

遇到问题：

今天在启动kafka后创建topic时遇到如下错误：

[hadoop@node01 kafka_2.11-2.4.1]$ bin/kafka-topics.sh --create --zookeeper node01:2181 --replication-factor 1 --partitions 1 --topic test
Exception in thread "main" kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING

 此时我的node01结点的kafka和zookeeper进程已经打开：

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
