```
执行org.apache.dubbo.config.DubboShutdownHook.destroyProtocols之前，已经执行了AbstractRegistryFactory.destroyAll()，
 
这个方法里已经去执行了zookeeperClient的close方法。参考：org.apache.dubbo.registry.zookeeper.ZookeeperRegistry#destroy
```
    @Override
    public void destroy() {
        super.destroy();
        try {
            zkClient.close();
        } catch (Exception e) {
            logger.warn("Failed to close zookeeper client " + getUrl() + ", 
cause: " + e.getMessage(), e);
        }
    }
```
