kinit: Keytab contains no suitable keys for ambari-qa@EXAMPLE.COM while getting initial credentials
WARNING: Use "yarn jar" to launch YARN applications.
The issue appears to be the wrong principal name in the kinit command - note the missing cluster name and realm in the principal name value.
/usr/bin/kinit -kt /etc/security/keytabs/smokeuser.headless.keytab ambari-qa
Cause
The error is caused by the use of the wrong variable when generating the kinit command at common-services/HIVE/0.12.0.2.0/package/scripts/hcat_service_check.py:44
{kinit_path_local} -kt {smoke_user_keytab} {smokeuser}
Solution
At common-services/HIVE/0.12.0.2.0/package/scripts/hcat_service_check.py:44, change smokeuser to smokeuser_principal.
