> There are a number of APIs that came in with MOB that are not new actions for HBase,
simply new actions for a MOB implementation:
> - compactMob
> - compactMobs
> - majorCompactMob
> - majorCompactMobs
> - getMobCompactionState
> And in HBaseAdmin:
> - validateMobColumnFamily
> Remove these special cases from the Admin API where possible by folding them into existing
APIs.
> We definitely don't need one method for a singleton and another for collections.
> Ideally we will not have any APIs named *Mob when finished, whether MOBs are in use on
a table or not should be largely an internal detail. Exposing as schema option would be fine,
this conforms to existing practice for other features.
> Marking critical because I think removing the *Mob special cased APIs should be a precondition
for release of this feature either in 2.0 or as a backport.
