Heng Chen commented on HBASE-14227:
-----------------------------------
How about this
{code}
+ /**
+ * {@code NORMAL} means do store files compaction;
+ * {@code MOB} means do mob files compaction.
+ * It is different, MOB compaction only take care of MOB files.
+ * Generally, MOB CF is larger than normal CF, a compaction on the MOB CF
will be more IO oriented than the normal CF.
+ * And the impact of the number of MOB files is not significant in read,
usually they are deleted when expired.
+ * So sometimes MOB compactions are not necessary. More MOB detail see
HBASE-11339
+ * */
+ public enum CompactType {
+
+ NORMAL (0),
+ MOB (1);
+
+ CompactType(int value) {}
+ }

> 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
> Assignee: Heng Chen
> Priority: Blocker
> Fix For: 2.0.0
>
> Attachments: HBASE-14227.patch, HBASE-14227_v1.patch,
> HBASE-14227_v2.patch, HBASE-14227_v3.patch

>
> 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.
