I've followed the Getting Started instructions for single node and it worked fine in cassandra-0.7beta2. But when trying to do the same for cassandra-0.7rc1 it spews out the following stack trace:

Someone posted this problem on cassandra's mailing list. It seems there's a problem, when trying to rename the tmp files (e.g. LocationInfo-tmp-e-1-Data.db). It happens in FBUtilities.java:
public static void renameWithConfirm(String tmpFilename, String filename) throws IOException
{
if (!new File(tmpFilename).renameTo(new File(filename)))
{
throw new IOException("rename failed of " + filename);
}
}
I should note that File.renameTo() is known to work funny on Windows.
Anyway... Help?
