Sorry for the late response, here is the latest patch. Let's see how it goes with HadoopQA
before preparing one compatible patch for branch-1

Thanks for the note [~tedyu]

> In HBASE-8329 we added a throughput controller for compaction, to avoid spike caused
by huge IO pressure like network/disk overflow. However, even with this control on, we are
still observing disk utils near 100%, and by analysis we think this is caused by flush, especially
when we increase the setting of {{hbase.hstore.flusher.count}}
> In this JIRA, we propose to add throughput control feature for flush, as a supplement
of HBASE-8329 to better control IO pressure.
