我已經按照單一節點的入門指示操作，並且它在cassandra-0.7beta2中正常工作。但是，試圖爲卡桑德拉 - 0.7rc1做同樣的，當它噴出了以下堆棧跟蹤：cassandra.bat拋出java.io.IOException：在0.7rc1中更名失敗LocationInfo-e -1 -Data.db

有人張貼在Cassandra的mailing list這個問題。 嘗試重命名tmp文件（例如LocationInfo-tmp-e-1-Data.db）時，似乎存在問題。 它發生在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);
}
}
我要指出，File.renameTo（）被稱爲是工作在Windows上搞笑。
無論如何...幫助嗎？
