    Description

      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:

      [root@ctr-e133-1493418528701-3077-01-000003 keytabs]# klist -kt hive.service.keytab
      Keytab name: FILE:hive.service.keytab
      KVNO Timestamp         Principal

      Given that 'hive.service.keytab' and 'hive.llap.zk.sm.keytab' contains the same principals, we can use 'hive.service.keytab' for copying principals to slider in HDFS.
