chenxu commented on HBASE-20740:
--------------------------------
{quote}Please describe your use case in more detail: how does coprocessor
generate requests (if there is no request from clients).
{quote}
what i means is that only *RSRpcServices#execService* are called, and
cpRequestCount means coprocessor service request count.
When performing heartbeat, _RegionLoad_s are report to the _HMaster_, but it
only contains readRequestsCount and writeRequestsCount and no cpRequestsCount,
so the balancer ignored cpRequestsCount factor.
Thank you for review this [[email protected]]
