> 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"
