Hi @Rasheed. You are right, to enable Kerberos Authentication you have to add the following configuration in hive-site.xml file:
<property>
<name>hive.server2.authentication</name>
<value>KERBEROS</value>
</property>
<property>
<name>hive.server2.authentication.kerberos.principal</name>
<value>hive/_HOST@YOUR-REALM.COM</value>
</property>
<property>
<name>hive.server2.authentication.kerberos.keytab</name>
<value>/etc/hive/conf/hive.keytab</value>
</property>
