since we upgraded half of our Cassandra cluster to 2.0.0 and we use LCS,
we hit CASSANDRA-6284 bug.
So the question. What is the best way to recompact all the sstables so
the data in one sstables within a level would contain more or less the
right portion of the data
Based on documentation, I can only think of switching to SizeTiered
compaction, doing major compaction and then switching back to LCS.
