Hairong Kuang updated HADOOP-2229:
----------------------------------
Attachment: ugi1.patch
On the second thought, I feel that getUMask() should not be part of the
UserGroupInformation (UGI) interface. One reason is that umask is not needed on
the server side and it does not need to be transferred over the wire. In the
new method, I removed getUMask from UGI, but UnixUserGroupInformation still
implements this method and umask gets saved into configuration.

> 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.
