stack resolved HBASE-2142.
--------------------------
Resolution: Duplicate
Marking duplicate of hbase-5325 which does better than this region asks for
giving you actual names of live and dead servers:
{code}
+ /**
+ * Get the live region servers
+ * @return Live region servers
+ */
+ public Map<String, HServerLoad> getRegionServers();
+
+ /**
+ * Get the dead region servers
+ * @return Dead region Servers
+ */
+ public String[] getDeadRegionServers();
{code}
> Add number of RegionServers (live/dead) to JMX metrics in HMaster

> While commenting on HBASE-2117 I noticed that Hadoop's NameNode has that and
