> Many path properties and similar in hadoop code base would be easily configured if we had substitutions with {{UserGroupInformation#getCurrentUser}}. Currently we often use less elegant concatenation code if we want to express currentUser as opposed to ${user.name} system property representing the user owning the JVM.
> This JIRA proposes the corresponding substitution support for keys {{ugi.current.user}} and {{ugi.login.user}}
