Pavel Yaskevich commented on CASSANDRA-4230:
--------------------------------------------
Yeah, it's only called in snapshotWithoutFlush so if you try to drop CF in the
middle of compaction snapshoting files it would be the only way to lead to such
behavior. I think what we need to do here is to stop compaction and run drop
after that...
> Deleting a CF always produces an error and that CF remains in an unknown state
