[~mkjellman] What else do you see about the file "evidence-fingerprints-ib-2183-Data.db" in
your log file? Can you see the file is compacted elsewhere?

> This is from discussion in CASSANDRA-5137. Currently we skip loading SSTables that are
left over from incomplete compaction to not over-count counter, but the way we track compaction
completion is not secure.
> One possible solution is to create system CF like:
> {code}
> create table compaction_log (
>   id uuid primary key,
>   inputs set<int>,
>   outputs set<int>
> );
> {code}
> to track incomplete compaction.
