[jira] Updated: (HADOOP-2229) Provide a simple login implementation

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

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.
