> Request rate at region server level can help identify the hot region server.
> But it will be good if we can further identify the hot regions on that region
> server. That way, we can easily find out unbalanced regions problem.
> Currently, readRequestCount and writeReqeustCount per region is exposed at
> webUI. It will be more useful to expose it through hadoop metrics framework
> and/or JMX, so that people can see the history when the region is hot.
> I am exposing the existing readRequestCount/writeRequestCount into the
> dynamic region level metrics framework. I am not changing/exposing it as rate
> because our openTSDB is taking the raw data of read/write count, and apply
> rate function to display the rate already.
