[jira] [Assigned] (SPARK-12646) Support _HOST in kerberos principal

> Components: YARN

> Hadoop supports _HOST as a token that is dynamically replaced with the actual hostname at the time the kerberos authentication is done. This is supported in many hadoop stacks including YARN. When configuring Spark to connect to secure cluster (e.g., yarn-cluster or yarn-client as master), it would be natural to extend support for this token to Spark as well.
