1) you have very high row variance and really really bad luck with the
distribution of your super-huge rows
2) you have repaired some nodes and not others, and have dramatically
over-repaired the repaired ones, possibly due to f/e TTL + repair issues in

The simple way to see if #2 is the case is to run a major compaction on a
good and a bad node. They should end up the same size.

There are operational implications to doing a major compaction, however, so
you might want to investigate the use of checksstablegarbage [1].
