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.
