HBASE-29119: Major compaction is disabled, but the webui shows that major compaction has been triggered

[wdzaslzy]

When major compaction is disabled, if all hfiles in a single region participate in compaction, they will be automatically marked as major compaction. I think this is wrong and contrary to the expected major compaction. In addition, according to the context, I found that as long as all hfiles participate in compaction, they are automatically deleted. I think this also needs to be adjusted.
