Owen O'Malley updated HADOOP-2229:
----------------------------------
Status: Open (was: Patch Available)
This looks pretty good. You need to fix the findbugs warnings and I'd make all
of the unix commands more standard (use whoami and groups) and make the
invoking path strings relative paths. Making them absolute makes it much more
likely to be wrong on non-linux platforms.

> 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.
