> snapshot race with compaction causes missing link error
> -------------------------------------------------------
>
> Key: CASSANDRA-6433
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6433
> Project: Cassandra
> Issue Type: Bug
> Environment: EL6
> Oracle Java 1.7.40
> Reporter: Karl Mueller
> Priority: Minor
>
> Cassandra 1.2.11
> When trying to snapshot, I encountered this error. It appears that snapshot doesn't lock the sstable list in a keyspace which can cause a race condition with compaction. (I think it's compaction, at least)
> [cassandra@dev-cass00 ~]$ cas cluster snap pre-1.2.12
> *** dev-cass01 (1) ***
>
> Nodetool command "snapshot -t pre-1.2.12" failed!
>
> Output:
>
> Requested creating snapshot for: all keyspaces
> Exception in thread "main" java.lang.RuntimeException: Tried to hard link to file that does not exist /data2/data-cassandra/csprocessor/csprocessor/csprocessor-csprocessor-ic-4-Summary.db
