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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
