Hairong Kuang updated HADOOP-2229:
----------------------------------
Attachment: ugi4.patch
Ok, now the proposal for umask to remove umask from both UGI and UnixUGI.
Instead FSPermission (defined in HADOOP-2288) is going to provide get/set umask
methods. The approach is that rather than getting a user's umask from UNIX,
umask is going to be read from hadoop configuration. If it is not set in the
configuration, it is set to a default value 0022.
This new patch reflects the proposed change.

> 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.
