Jakob Homan updated HDFS-462:
-----------------------------

    Attachment: HDFS-462.patch

Attaching patch that fixes problem.  Konstantin tested on his Windows box and it worked. 
Passes unit tests.  Nicholas, I don't believe your issue is due to this problem, but rather
from the URI patch that's related to this one.

> Unit tests are failing on windows due to a problem with rename. 
> The failing code is around line 520 in FSImage.java: 
> {noformat}
>       assert curDir.exists() : "Current directory must exist.";
>       assert !prevDir.exists() : "prvious directory must not exist.";
>       assert !tmpDir.exists() : "prvious.tmp directory must not exist.";
>       // rename current to tmp
>       rename(curDir, tmpDir);
>       // save new image
>       if (!curDir.mkdir())
>         throw new IOException("Cannot create directory " + curDir);
> {noformat}
> and seems related to some open file or directory
