在赫克托尔，我得到一个HTimedOutException，我假设是因为卡桑德拉的SSTable腐败，因为它在电源故障之前运作良好。我该如何解决？这也是开发数据库，我之前遇到过这个问题并最终删除了一些列系列，但我不希望这是每次断电或系统崩溃时唯一的解决方案。我正在使用cassandra 1.2.2

Answer 1

您可以删除损坏的SSTable，然后运行修复以从副本中恢复数据，而不是删除整个CF.问题是错误不会在日志中打印文件名，因此很难找出哪个文件已损坏。您可以通过在调试模式下运行Cassandra来获取它（编辑log4j-server.properties）。见另一篇SO帖子：

Error messages while starting Cassandra node

他们是如何做到的。

Answer 2

首先要尝试的是nodetool scrub这个cf（例如，参见this post for v.1.2）。

电源故障后，某些查询会抛出Cassandra EOFException
