My impression is that force GC should have deleted the SSTable files no longer valid.
I performed a nodetool compact, all went good and finished. All column family now only have one big live SSTable file. Then I use jconsole to force a GC, but those old SSTable files still not getting deleted. I thought this should trigger a deletion for those SSTable files maked for delete. I'm using 0.7-rc2. When I perform the force GC, no exception in log file.
