Yu Li commented on HBASE-14969:
-------------------------------
Thank you for the double check sir [~ghelmling]
bq. If the change wasn't intentional, maybe we should do a small follow up
issue to change the default back. Even better if we remove the duplicate class
and just use one.
Yes you are right, it was my fault not being carefully enough when preparing
the patch for branch-1 (sorry about this...). The one in o.a.h.h.compactions
should be removed, and we should change the default back to
{{NoLimitThroughputController}} for branch-1. I'll open another JIRA to fix
this, and thank you for pointing out the issue.

> 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.
