Java connection to zookeeper is slow

I have been learning zookeeper recently, but it is very slow to connect to the zookeeper server, more than 18s each time.

I tried to search the question in the headline and found the answer.

The reason is that when the server is clustered, the host is set to use hostname instead of ip, and the client does not configure the mapping of hostname and ip.

Because you are running multiple projects on one tomcat, the first two projects went wrong when deployed successfully to the third one. Then you compared the differences among the three configuration files and found that the problem lies in the fact that id is tzydZk. So ping found that ping is not available at this address, indicating that there is a problem with the server. As a result, the server address has been changed.

I'm speechless. Change the address to the new server address and get it done.
