Pavel Yaskevich updated CASSANDRA-4221:
---------------------------------------
Attachment: CASSANDRA-4230.patch
Patch adds a try to stop all running compactions on given Keyspace or
ColumnFamily before running a drop command. I have tried the test you have in
the description and it ran without failures.
> Error while deleting a columnfamily that is being compacted.
