ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

啓動kafka的時候報錯，找了很久，特以此記錄。

我一直在糾結於這個錯誤。

ERROR Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)

最後纔看到下面這行，顯示zookeeper連接超時

kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection

然後我修改了一下server.properties文件裏的超時時間，就ok了

zookeeper.connection.timeout.ms=60000
