Subject [jira] Commented: (HADOOP-2229) Provide a simple login implementation
Date Thu, 29 Nov 2007 23:09:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2229?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12546932
] 

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.
