Hive-Servers are managed via Zookeeper, so you can connect to Zookeeper ...

zookeeper-client -server <zookeeper-server>

...and read the "hiverserver2" Znode (Note: the Znode is configured via hive.server2.zookeeper.namespace)

ls /hiveserver2

As a result you get all the available Hive-Servers

[serverUri=horton02.example.com:10000;version=1.2.1.2.3.2.0-2950;sequence=0000000014, serverUri=horton03.example.com:10000;version=1.2.1.2.3.2.0-2950;sequence=0000000015]

To view the registered hiveservers you can use the zkCli.

$ /usr/hdp/current/zookeeper-client/bin/zkCli.sh
[zk: localhost:2181(CONNECTED) 0] ls /hiveserver2
[serverUri=node-1.example.com:10000;version=x.x.x.2.3.2.0-xx;sequence=0000000000]
