cassandra.bat抛出java.io.IOException：在0.7rc1中重命名LocationInfo-e -1-Data.db失败

我已经按照单节点的入门说明进行操作，它在cassandra-0.7beta2中运行良好 . 但是当尝试为cassandra-0.7rc1做同样的事情时，它会喷出以下堆栈跟踪：

有人在cassandra的mailing list上发布了这个问题 . 在尝试重命名tmp文件时（例如，LocationInfo-tmp-e-1-Data.db），似乎存在问题 . 它发生在FBUtilities.java中：

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);
        }
    }

我应该注意到，File.renameTo（）在Windows上工作很有趣 .

无论如何......救命？
