Dave Latham commented on HBASE-14227:
-------------------------------------

I'm not a fan of passing behavior arguments as special in band names for 
something like a column family.  It leads to worse documentation, user 
surprises, and potentially even conflicts if someone already has such a column 
family.  Since MOB compaction actually is a separate thing, it should be 
reflected in the API by either another parameter or new API methods (though 
they should be minimized).  But just my two cents from an interested user.

> Fold special cased MOB APIs into existing APIs

>          Issue Type: Task
>          Components: mob
>    Affects Versions: 2.0.0

>            Priority: Blocker
>             Fix For: 2.0.0

> 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.
