kafka.zookeeper.ZooKeeperClientTimeoutException：在状态下等待连接超时：在 Windows 上连接

编程问答 2022-05-24

问题描述

我正在尝试在我的 Windows 机器上启动 apache 服务器。但是这样做时我收到此错误 Transport transport = message.getTransport(address); try{ transport.connect(); }catch (Exception e){ //already connected } transport.sendMessage(message); 并且进程停止。请注意，我在运行之前启动了 zookeeper 进程，并且启动正常。

zookeeper 的控制台日志如下：-

kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection while in state: CONNECTING

kafka 服务器启动时在控制台登录错误：-

从日志看来，定义了 18000 毫秒的超时。奇怪的是，几分钟后，当我再次启动 kafka 服务器进程时，我能够毫无问题地启动它。请注意，我从 kafka 包中提供的 zookper-server-start.bat 而不是 apache zookeeper 包中启动了 zookeeper。

谢谢
