Yu Li commented on HBASE-14969:
-------------------------------

Checking the findbugs warning, none is introduced by the patch here.

For the two "Increment of volatile field" warnings in HRegion, since the 
increment is inside a synchronized block, it's not a problem.

For the "Result of integer multiplication cast to long" one, have opened 
HBASE-15117 to resolve it.

> 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.
