   Find some time to debug the issue. It seems to only affects Windows. The root cause is that zookeeper clients invoke `InetAddress#getHostName()` when connecting to remote nodes. The method involves host name resolution, which may be very slow under Windows. The error stack is actually a timeout error.
   
   And here are the workarounds:
   Option1: Enlarge timeout value:
   ```
   dubbo.registry.timeout=30000
   dubbo.registry.parameters.blockUntilConnectedWait=30
   ```
   Option2: Add addresses of zookeeper nodes to the local `hosts` file.
