Subject: [jira] Updated: (HADOOP-2371) Candidate user guide for permissions
 feature of Hadoop DFS

Robert Chansler updated HADOOP-2371:
------------------------------------

    Fix Version/s: 0.16.1
      Description: 
This feature introduces a POSIX-like permissions model for DFS in Hadoop 0.16. The user guide describes the behavior users of DFS will experience. In this release, the user identity model is very elementary: you are who your host says you are. It is understood that this is not "secure" in any meaningful sense, but rather the permissions model allows a cooperative community to share file system resources in an organized fashion. The user identity model will evolve in the coming months.

As mentioned in the draft, the content of the guide will be incorporated into the regular Hadoop documentation from Forrest. This document is being published as an early preview.
