------------------------------------

             Summary: Implement a distributed MOB compaction by procedure
                 Key: HBASE-15381
                 URL: https://issues.apache.org/jira/browse/HBASE-15381
             Project: HBase
          Issue Type: Improvement
          Components: mob
            Reporter: Jingcheng Du
            Assignee: Jingcheng Du


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.
