> The Smoke and “Headless” Service users are used by Ambari to perform service
> “smoke” checks and run alert health checks.
> The permission for hdfs.headless.keytab is 440. But it will cause security
> concern to allow other service user in hadoop group to kinit hdfs headless
> principal using hdfs.headless.keytab. In this way, other service user could
> "pretend" to be hdfs user and be granted hdfs user's authorities.
