Subject Re: Deleting "old" SSTables

Force a GC to remove the unused sstables. Use something like jconsole or cmd
line "jmap -histo:live <pid>". You would run the jmap command as the
cassandra user or root. The jmap will give you a bunch of output on live
objects in the heap if you choose to look at it.
