尝试修复密钥空间时遇到问题：

myuser@host-1:~$ nodetool repair -pr mykeyspace
[2014-11-07 13:33:10,132] Starting repair command #13, repairing 1 ranges for keyspace mykeyspace

[2014-11-07 13:33:20,668] Repair command #13 finished

当我看着system.log它host-1说：

当我查看日志时，X.X.X.33我看不到任何日志错误。

谁能给我指点正确的方向？

    固定的。我发布了一份手册nodetool snapshot mykeyspace，X.X.X.33并设法在日志中找到了更好的错误。原来我有一个丢失的数据文件，可能是由于删除表并创建它的速度比架构更改在整个集群中传播的速度更快。重新启动 Cassandra 节点（以便它发现文件丢失）并截断表。
