> Multiple RS can run on the same host. But in current RegionLocationFinder, mapHostNameToServerName map one host to only one server. This will make LocalityCostFunction get wrong locality about region.
> {code}
> // create a mapping from hostname to ServerName for fast lookup
> HashMap<String, ServerName> hostToServerName = new HashMap<String, ServerName>();
> for (ServerName sn : regionServers) {
> hostToServerName.put(sn.getHostname(), sn);
> }
