Subject Re: Cassandra isn't compacting old files

I don't have time to dive deep into the code of your version, but it may be
( https://issues.apache.org/jira/browse/CASSANDRA-13620 ) , or it may be
something else.

I wouldn't expect compaction to touch them if they're invalid. The handle
may be a leftover from trying to load them.
