so,I delete the sstable cassandra_uc_log-log_user-ka-7611-Data.db than do repair,but it throws a new excepiton:
Repair session f33a4b10-ffb7-11e5-8fe3-31b2e5b5b0b2 for range (-5651751204441903619,-5621122634670931727] failed with error java.io.IOException: Failed during snapshot creation.
how can I repair or rebuild the sstable cassandra_uc_log-log_user-ka-7611-Data.db
I'm afraid you'll have to restart the node with the file deleted. Next time you may also try to run nodetool scrub with the corrupted sstable in place.
You haven't mentioned your Cassandra version, but assuming you're using incremental repairs with Cassandra 2.1+ you may also have to do a full repair in case the sstable was already in the repaired state.
