on JIRA as well.

bq. You can add a getter in MasterServices for MasterMobCompactionManager (to
be renamed MobCompactionManager).
This manager is not used for RPC calls (only for local reference and local
call), is it okay to add it to MasterServices?

> In MOB, there is a periodical compaction which runs in HMaster (It can be
> disabled by configuration), some small mob files are merged into bigger ones.
> Now the compaction only runs in HMaster which is not efficient and might
> impact the running of HMaster. In this JIRA, a distributed MOB compaction is
> introduced, it is triggered by HMaster, but all the compaction jobs are
> distributed to HRegionServers.
