> Currently, the first cut of mob will have external processes to age off old mob data
(the ttl cleaner), and to compact away deleted or over written data (the sweep tool).  
> From an operational point of view, having two external tools, especially one that relies
on MapReduce is undesirable.  In this issue we'll tackle integrating these into hbase without
requiring external processes.
