> 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.
