此错误的原因是什么？如何修复？感谢您的支持。老实说，这可能是卡桑德拉的一个错误。出于好奇，当你在CL-One做请求时会发生什么？另外，您是否对sstables进行了cassandra升级？MS：请参见上面的编辑。你所说的cassandra升级sstables是什么意思？基本上，如果你在cassandra的早期版本中有数据，那么当你升级时，你可能也升级了sstables。根据之前提供的信息，这实际上可能是cassandra 3.9中的一个bug。如果您有选择的话，我建议您恢复旧版本的cassandra并尝试相同的查询。还有一个问题，您是如何运行cassandra的？它是单个实例还是多个实例？您还可以提供
