> Project: Ambari
> Issue Type: Bug
> Reporter: Swapan Shridhar
> Assignee: Swapan Shridhar
>
> *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.
