> Key: SPARK-6558
> URL: https://issues.apache.org/jira/browse/SPARK-6558
> Project: Spark

> Components: Spark Core
> Affects Versions: 1.3.0
> Reporter: Thomas Graves

> Fix For: 1.4.0

>
> 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 us...@corp.com).
> 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()
