Candidate user guide for permissions feature of Hadoop DFS
----------------------------------------------------------
Key: HADOOP-2371
URL: https://issues.apache.org/jira/browse/HADOOP-2371
Project: Hadoop
Issue Type: New Feature
Components: dfs
Affects Versions: 0.16.0
Reporter: Robert Chansler
Assignee: Robert Chansler
Fix For: 0.16.0
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.
