Yu Li commented on HBASE-14969:
-------------------------------
The two findbugs issues don't need to handle as mentioned before.
The hadoopcheck issue is tracked by HBASE-15103, we could see the same error in
log:

> 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.
