Ted Yu commented on HBASE-20740:
--------------------------------
bq. only have coprocessor requests
Please describe your use case in more detail: how does coprocessor generate
requests (if there is no request from clients).
{code}
+ * @return the number of write requests made to region
+ */
+ public long getCpRequestCount();
{code}
javadoc says write requests but the method name doesn't reflect such (implying
read+write). Please go over the patch and make the method name(s) match
semantics you want.
Please upload next patch to review board.
> StochasticLoadBalancer should consider Coprocessor request count when
> computing cost
