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

遇到問題：

今天在啟動kafka后創建topic時遇到如下錯誤：

[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

 此時我的node01結點的kafka和zookeeper進程已經打開：

 

問題解決：

這是因為自己已經搭建了zookeeper集群。如果只啟動單台服務器zookeeper在選舉的時候將不可進行。所以zookeeper就會認為服務處於不可用狀態。將node02和node03節點的zookeeper全部啟動后創建topic成功
