如何在不重启cassandra节点的情况下重建sstable？

当我在一个节点上做一个紧凑的工作时，它会抛出以下异常：

所以，我删除sstable cassandra_uc_log-log_user-ka-7611-Data.db而不是修复，但是它会抛出一个新的例外：

Repair session f33a4b10-ffb7-11e5-8fe3-31b2e5b5b0b2 for range (-5651751204441903619,-5621122634670931727] failed with error java.io.IOException: Failed during snapshot creation.

如何修复或重建sstable cassandra_uc_log-log_user-ka-7611-Data.db
