We can introduce metrics2 package and put MasterMetrics.java there, what do you 
think ?
{code}
+
+public class TestMasterMetrics {
{code}
The above class is a small test, right ?

I assume, once complete, the Metrics2 metrics would substitute old metrics.

> Metrics Framework has been marked deprecated in Hadoop 0.20.203+ and 0.22+, 
> and it might get removed in future Hadoop release.  Hence, HBase needs to 
> revise the dependency of MetricsContext to use Metrics2 framework.
