[SPARK-6558] Utils.getCurrentUserName returns the full principal name
instead of login name
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 [email protected]).
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()
