That doesn't make sense to me. CS:147 is
columnFamilyKeyMap.put(row.key, row.cf);
where cFKM is
Map<DecoratedKey, ColumnFamily> columnFamilyKeyMap = new
HashMap<DecoratedKey, ColumnFamily>();
So cFKM can't be null, and HashMap accomodates both null key and null
value, so I'm not sure what there is to thorw NPE.
