Propagate compaction status from HRegion to HRegionInfo
-------------------------------------------------------

                 Key: HBASE-3943
                 URL: https://issues.apache.org/jira/browse/HBASE-3943
             Project: HBase
          Issue Type: Bug
          Components: master, regionserver
            Reporter: Ted Yu
            Assignee: Ted Yu


Load balancer works with HRegionInfo. However, compaction status is contained in HRegion.WriteState

Users reported the following (Schubert Zhang):

1. A region have many files, the compacting takes long time.
2. But the balancer (default 5 minutes) close and move this region to
another server.
3. Then, the compacting start again.
4. Then, then balancer close and move it to another server.

Thus, the compacting cannot complete.
Now, we set the balancer interval to 30 minutes to remission this issue.

We need to propagate compaction status to HRegionInfo so that load balancer doesn't move the
region being compacted.
