Swapan Shridhar updated AMBARI-22472:
-------------------------------------
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.

> Ambari Upgrade 2.5 -> 2.6 : Update NodeManager's HSI identity 'llap_zk_hive'
> to use '/HIVE/HIVE_SERVER/hive_server_hive' reference instead of creating the
