PROBLEM:

After upgrade from IOP (v 4.2.5) to HDP (v 2.6.x) in a kerberized setup, HSI start fails with following in HSI start log :

Correspondingly, from LLAP YARN application log, we see the following:

REASON : After IOP-HDP upgrade, the keytab file permissions for "hive.llap.zk.sm.keytab" is only owner readable.

# ls -al /etc/security/keytabs/hive.llap.zk.sm.keytab 
-r--------. 1 yarn      hadoop  428 Aug 15 19:34 hive.llap.zk.sm.keytab

Thus, hive user is not able to access hive.llap.zk.sm.keytab.

The group not having read permission is because IOP kerberos.json file for YARN have permissions removed for it.

FIX: Regenerating keytabs via Ambari fixes the permission issue, as hive user can now access the keytabs being part of hadoop group.

# ls -al /etc/security/keytabs/hive.llap.zk.sm.keytab 
-r--r-----. 1 yarn hadoop 428 Aug 15 20:26 hive.llap.zk.sm.keytab

- Once regeneration is done, start HSI again.

P.S. : Hive Server Interactive is made up of 2 sub-components : LLAP and Hive2/HiveServer2.
