> 是否是zookeeper环境问题
我也遇到这个问题，在windows上面能重现，就用网站的例子，只加一个zookeeper的地址就能重现，但是代码在centos上面运行是正常的，在windows idea 的debug模式下，在 org.apache.dubbo.remoting.zookeeper.curator.CuratorZookeeperClient 类内部 this.client.start(); 执行后，断点等一会就运行正常了 。如果不配置dubbo.config-center.timeout , 超时时间是3000，配置后是5000，我感觉是zookeeper客户端的问题，我的zookeeper服务端是3.5.5 。
