how to set dynamic service discovery for HiveServer2

[Allen]

hi,all

I want to use dynamic service discovery for HiveServer2.

I has already set some configuration parameters about  dynamic service 
discovery in hive-site.xml. The hive server2 has been started in two 
machines,and these nodes has register itself in zk. 

       But I don’t know how to use it in beeline.

Can anybody tell me how to write the connection url ?

Thanks.‍‍
