--------------------------------

Integrated in Hadoop-Common-trunk-Commit #150 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-Common-trunk-Commit/150/])
    . Reimplement the UserGroupInformation to use the OS

> Currently we use a custom login module in UnixUserGroupInformation for acquiring user-credentials
(via config or exec'ing 'whoami'). We should switch to using standard JAAS components such
as LoginContext and possibly implement a custom UnixLoginContext for our current requirements.
In future we can use this for Kerberos etc.
