cassandra.bat抛出java.io.IOException:0.7rc1中LocationInfo-e-1-Data.db的重命名失败

我遵循了单节点的入门说明，它在cassandra-0.7beta2中运行良好。但当尝试对cassandra-0.7rc1执行相同操作时，它会输出以下堆栈跟踪：

INFO 20:21:37,771 Starting up server gossip INFO 20:21:37,786 switching in a fresh Memtable for LocationInfo at CommitLogContext(file='/var/lib /cassandra/commitlog\CommitLog-1290885697489.log', position=700) INFO 20:21:37,786 Enqueuing flush of Memtable-LocationInfo@29247351(227 bytes, 4 operations) INFO 20:21:37,786 Writing Memtable-LocationInfo@29247351(227 bytes, 4 operations) ERROR 20:21:38,161 Fatal exception in thread Thread[FlushWriter:1,5,main] java.io.IOError: java.io.IOException: rename failed of D:\var\lib\cassandra\data\system\LocationInfo-e-1-Data.db at org.apache.cassandra.io.sstable.SSTableWriter.rename(SSTableWriter.java:214) at org.apache.cassandra.io.sstable.SSTableWriter.closeAndOpenReader(SSTableWriter.java:184) at org.apache.cassandra.io.sstable.SSTableWriter.closeAndOpenReader(SSTableWriter.java:167) at org.apache.cassandra.db.Memtable.writeSortedContents(Memtable.java:161) at org.apache.cassandra.db.Memtable.access$000(Memtable.java:49) at org.apache.cassandra.db.Memtable$1.runMayThrow(Memtable.java:174) at org.apache.cassandra.utils.WrappedRunnable.run(WrappedRunnable.java:30) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: java.io.IOException: rename failed of D:\var\lib\cassandra\data\system\LocationInfo-e-1-Data.db at org.apache.cassandra.utils.FBUtilities.renameWithConfirm(FBUtilities.java:359) at org.apache.cassandra.io.sstable.SSTableWriter.rename(SSTableWriter.java:210) ... 12 more 我应该注意到，众所周知，File.renameTo（）在Windows上的工作非常有趣

无论如何。。。帮助？

请在此处创建错误报告：

public static void renameWithConfirm(String tmpFilename, String filename) throws IOException
    {
        if (!new File(tmpFilename).renameTo(new File(filename)))
