> Give a simple implementation of HADOOP-1701.    Hadoop clients are assumed to be started
within a Unix-like network which provides user and group management.  This implementation
read user information from the OS and send them to the NameNode in plaintexts through RPC
(see also HADOOP-2184).  NameNode trusts all information given and uses them for permission
checking.
