Anoop Sam John commented on HBASE-14227:
----------------------------------------
It is not that straight forward change. When we call compact <table> <cf>
there is a column family for the (normal HBase cf) reference cells which refers
to MOB cells. And there is another MOB CF. A compaction on the MOB CF will be
more IO oriented than the normal CFs. So when we call compact whether the
compaction has to happen for the ref CF or MOB CF or both? May be instead of
new APIs as above, it would have been like overloaded APIs with a boolean param
which says whether to compact/major compact the MOB CF also? Then there is no
need for new CP hooks and the security checks also can be enforced.
> Fold special cased MOB APIs into existing APIs

> Key: HBASE-14227
> URL: https://issues.apache.org/jira/browse/HBASE-14227
> Project: HBase
> Issue Type: Task
> Components: mob
> Affects Versions: 2.0.0
> Reporter: Andrew Purtell
> 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.
