> hive.server2.authentication.kerberos.principal set in the form of hive/_HOST@REALM,
> Tez task can start at the random NM host and unfold the value of _HOST with the value
of fqdn where it is running. this leads to an authentication issue.
> for LLAP there is fallback for LLAP daemon keytab/principal, Kafka 1.1 onwards support
delegation token and we should take advantage of it for hive on tez.
