Subject [jira] [Commented] (HBASE-14227) Fold special cased MOB APIs into existing APIs
Date Sat, 15 Aug 2015 17:28:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14698364#comment-14698364
] 

Andrew Purtell commented on HBASE-14227:
----------------------------------------

Another strong reason for doing this work is there is no coprocessor API nor AccessController
support for securing the MOB admin APIs. 

Adding APIs specific to MOB could be reasonable at the coprocessor level, I think we'd want
to look at that on a case by case basis, and again avoid wherever possible.

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

>            Priority: Critical
>             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.
