我在尝试修复密钥空间时遇到了一个问题：
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 session 3baeeb40-667a-11e4-a6e9-3562b4c30e9e for range (-3651079129967449,-2] failed with error java.io.IOException: Failed during snapshot creation. [2014-11-07 13:33:20,668] Repair command #13 finished 当我在host-1上查看system.log ，它说：

当我查看XXX33上的日志时，我没有看到任何日志错误。
任何人都可以给我指向正确的方向？
固定。 我在nodetool snapshot mykeyspace上发布了一个手动的nodetool snapshot mykeyspace ，并设法在日志中获得更好的错误。 事实certificate，我有一个丢失的数据文件，可能是从表中删除一个表，并创build它比在整个集群传播的架构更改更快。 重新启动Cassandra节点（为了发现文件丢失）和TRUNCATEd表。
