> Wrong compaction report and assert when MOB compaction switches to minor

> Key: HBASE-12030
> URL: https://issues.apache.org/jira/browse/HBASE-12030
> Project: HBase
> Issue Type: Bug
> Components: Compaction, regionserver
> Affects Versions: hbase-11339
> Reporter: Matteo Bertozzi
> Priority: Critical
> Fix For: hbase-11339

>
> when zookeeper is down during a major compaction or a sweep tool run in
> progress, we switch to a minor.
> {code}
> try {
> zk = MobZookeeper.newInstance(this.conf, compactionName);
> } catch (KeeperException e) {
> LOG.error("Cannot connect to the zookeeper, ready to perform the minor
> compaction instead", e);
> // change the major compaction into a minor one
> compaction.getRequest().setIsMajor(false);
> return super.compact(compaction);
> }
> {code}
> but the "request start" (HRegion.reportCompactionRequestStart) is "major" and
> increments the major-compactions counter
> while the "request end" (HRegion.reportCompactionRequestEnd) is "minor" and
> decrements the minor-compactions counter
> triggering the assert newValue >= 0, since we are decrementing the wrong
> counter
