> Requests counter showing negative count, example under 'Requests' column:
> -645470239
> {code}
> Name Region Server Start Key End Key Requests

> -645470239
> {code}
> RegionLoad.readRequestsCount and RegionLoad.writeRequestsCount are of int
> type. Our Ops has been running lots of heavy load operation.
> RegionLoad.getRequestsCount() overflows int.MAX_VALUE. It is set to D986E7E1.
> In table.jsp, RegionLoad.getRequestsCount() is assigned to long type.
> D986E7E1 is converted to long FFFFFFFFD986E7E1 which is -645470239 in decimal.
> Suggested fix is to make readRequestsCount and writeRequestsCount long type.
