Description

Utils.getCurrentUserName returns UserGroupInformation.getCurrentUser().getUserName() when SPARK_USER isn't set. It should return UserGroupInformation.getCurrentUser().getShortUserName()

getUserName() returns the users full principal name (ie [e-mail]). getShortUserName() returns just the users login name (user1).

This just happens to work on YARN because the Client code sets:
env("SPARK_USER") = UserGroupInformation.getCurrentUser().getShortUserName()
