Subject [jira] [Resolved] (CASSANDRA-9595) Compacting an empty table sometimes doesn't delete SSTables in 2.0 with LCS

Marcus Eriksson resolved CASSANDRA-9595.
----------------------------------------
    Resolution: Not A Problem

Looks like the dtest does a major compaction which we don't support with LCS until 2.2

> On 2.0, when compaction is run on a table with all rows deleted and configured with LCS,
sometimes SSTables remain on disk afterwards. This causes one of our dtests to fail periodically,
for instance [here|http://cassci.datastax.com/view/cassandra-2.0/job/cassandra-2.0_dtest/68/testReport/compaction_test/TestCompaction_with_LeveledCompactionStrategy/sstable_deletion_test/].
This can be reproduced in dtests with
> {code}
> CASSANDRA_VERSION=git:cassandra-2.0 nosetests ./compaction_test.py:TestCompaction_with_LeveledCompactionStrategy.sstable_deletion_test
> {code}
