Subject [jira] [Updated] (HADOOP-8235) Support file permissions and ownership on Windows for RawLocalFileSystem
Date Thu, 24 May 2012 22:01:35 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8235?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Chuan Liu updated HADOOP-8235:

    Status: Patch Available  (was: Open)

In this patch, we create a native Windows console program to emulate certain Linux command
line utilities that are used by Hadoop to set file permissions, ownership, and query file
status. The Windows program does not support full command line semantic and functionalities
as the equivalent Linux commands. We only provide enough support for the Hadoop usage. The
source code can be built on Windows with all versions of Visual Studio 10, including Visual
Studio Express 10. The solution file and project file are also generated in Visual Studio
10. (Note for Visual Studio Express: Visual Studio Express does not include compiler for X64
platform. To build on X64 platform, Windows SDK is needed.)

Corresponding Java code, e.g. Shell.java, are also modified for Hadoop to pick up the correct
commands on Windows. There are also a few file permission related test fixes due to different
OS behaviors.

This is just an initial patch for review and collecting feedbacks from community.

We will later adding tests for the Windows program and make changes based on the feedbacks.

> The initial patch submitted on HADOOP-8223 does not have ability to set file permissions
on Windows. This is causing tests to fail. Jira tracks adding support to enable file permissions
and ownership changes on Windows
