> **Background:**
> YARN NodeManager currently has:
> - 2 identities in 2.5 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.
> - and 3 identities in 2.6 stack:
> *'/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** and **llap_task_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:**
> **For HDP 2.5:** Make **llap_zk_hive** 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.
> **For HDP 2.6:** Make **llap_zk_hive** and **llap_task_hive** 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.
