Jingcheng Du commented on HBASE-15381:
--------------------------------------
And I think if the distributed mob compaction is committed, the sweep tool can
be removed from the code.
> Implement a distributed MOB compaction by procedure

>
> 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.
