Review comment:
Kyuubi use configuration (`kyuubi.kinit.principal abc/[email protected]`)
The data published by service1 to znode is `abc/[email protected]`
The data published by service2 to znode is `abc/[email protected]`
The client connects to different nodes and uses different principals as
parameters.

```java
if
(matcher.group(1).equalsIgnoreCase("hive.server2.authentication.kerberos.principal")
&& ... ){
connParams.getSessionVars().put(JdbcConnectionParams.AUTH_PRINCIPAL,
matcher.group(2));
}
```
org.apache.hive.jdbc.HiveConnection
```java
if (sessConfMap.containsKey(JdbcConnectionParams.AUTH_PRINCIPAL)) {
transport = KerberosSaslHelper.getKerberosTransport(
sessConfMap.get(JdbcConnectionParams.AUTH_PRINCIPAL), host,
socketTransport, saslProps, assumeSubject);
