Doug Cutting commented on HADOOP-2229:
--------------------------------------

Why is umask only a Unix feature, rather than in the interface?

Also, it seems to me that perhaps umask should use the api from HADOOP-2288, exposing itself as an FsPermission, or at least linking to that in the javadoc, so that one knows how to use that value.

> 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.
