> *Issue:*
> HSI server start failed with "kinit: Key table file
> '/etc/security/keytabs/hive.llap.zk.sm.keytab' not found while getting
> initial credentials".
> *Reason:*
> This can happen when HSI is placed on a node where YARN's NodeManager node
> doesn't exists. Thus, 'hive.llap.zk.sm.keytab' file wont get generated.
> *Fix:*
> Following are the principals in both keytab files:
