             Summary: hive on Tez :  Kafka storage handler broken in secure environment
                 Key: HIVE-23408
                 URL: https://issues.apache.org/jira/browse/HIVE-23408
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 4.0.0
            Reporter: Rajkumar Singh


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.
