Subject Building branch-1-win, Starting Datanode on Windows
Date Mon, 04 Mar 2013 14:55:38 GMT
Hi all,

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
are invalid.

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.
