Hudson commented on HADOOP-4429:
--------------------------------
Integrated in Hadoop-trunk #670 (See
[http://hudson.zones.apache.org/hudson/job/Hadoop-trunk/670/])
. Set defaults for user, group in UnixUserGroupInformation so
login fails more predictably when misconfigured. Contributed by Alex
Loddengaard.
