> Skip compaction request/check for replica regions at the early stage.

> Key: HBASE-24581
> URL: https://issues.apache.org/jira/browse/HBASE-24581
> Project: HBase
> Issue Type: Improvement
> Components: read replicas
> Affects Versions: 2.3.0
> Reporter: Huaxiang Sun
> Assignee: Huaxiang Sun
> Priority: Major
>
> I found that in certain cases replica regions can trigger compaction, one
> example as follows, need to check all places to avoid compaction for replica
> regions.
> {code:java}
> @Override
> public void postOpenDeployTasks(final PostOpenDeployContext context) throws
> IOException {
> HRegion r = context.getRegion();
> long openProcId = context.getOpenProcId();
> long masterSystemTime = context.getMasterSystemTime();
> rpcServices.checkOpen();
> LOG.info("Post open deploy tasks for {}, openProcId={},
> masterSystemTime={}",
> r.getRegionInfo().getRegionNameAsString(), openProcId, masterSystemTime);
> // Do checks to see if we need to compact (references or too many files)
> // TODO: SHX, do not do this for replica regions? Otherwise, it is going to
> lost data locality for primary regions.
> for (HStore s : r.stores.values()) {
> if (s.hasReferences() || s.needsCompaction()) {
> this.compactSplitThread.requestSystemCompaction(r, s, "Opening Region");
> }
> }
> {code}
