Bugs: AMBARI-22472
https://issues.apache.org/jira/browse/AMBARI-22472
Repository: ambari
Description
-------
**Background:**
YARN NodeManager currently have 2 identities in 2.5 and 2.6 stack, namely :
*'/HIVE/HIVE_SERVER/hive_server_hive'* and *'llap_zk_hive'*.
- */HIVE/HIVE_SERVER/hive_server_hive* is a reference from HIVE_SERVER, whereas
- *llap_zk_hive* creates same principal as above in a separate keytab file.
**Issue:** Recreating same identities in different files creates issues while
AMbari upgrade from 2.5 to 2.6, as the *llap_zk_hive* are not refreshed/updated
after the upgrade. Thus, HSI fails to come up.
**Fix:** Make * llap_zk_hive* also point as a reference pointing to
/HIVE/HIVE_SERVER/hive_server_hive, so that we have one identity getting
created only at one place and one keytab file.
