I don't think you need to manually set permissions on Hadoop directories.
Did you build the native windows executable in your build? Do you see any
exceptions mentioning winutils?

Subject: Building branch-1-win, Starting Datanode on Windows
I've cloned the branch-1-win branch of Hadoop, and successfully managed to
build it on my Windows 8 machine.
When trying to start a datanode instance, I get the following error:
13/03/04 14:42:47 WARN datanode.DataNode: Invalid directory in
dfs.data.dir: Incorrect permission for C:/hadoop/data, expected:
rwxr-xr-x, while actual: ------rwx
13/03/04 14:42:47 ERROR datanode.DataNode: All directories in dfs.data.dir
The directory exists, and I've set "Allow all" to Everyone.
Is this an issue that should exist in the Windows branch? Is there a way
to massage Windows' file permissions into something the datanode will
accept without further modifications to the code?
Many thanks in advance.
