> While initializing RSRpcServices server name is formed as,
> {code}
>     String name = rs.getProcessName() + "/" + initialIsa.toString();
> {code}
> So name will be like "regionserver/host_Name/host_IP:port".
> During MetricsHBaseServer intializing, we create server context name using String contains()
which will be wrong when machine hostname contain "master" words.
> In MetricsHBaseServerSourceFactory, 
> {code}
>   protected static String createContextName(String serverName) {
>     if (serverName.contains("HMaster") || serverName.contains("master")) {
>       return "Master";
>     } else if (serverName.contains("HRegion") || serverName.contains("regionserver"))
{
>       return "RegionServer";
>     }
>     return "IPC";
>   }
> {code}
> For example, "regionserver/node-master1-xyz/host-IP:16020"
