Subject [jira] [Resolved] (HBASE-2142) Add number of RegionServers (live/dead) to JMX metrics in HMaster
Date Fri, 24 Feb 2012 20:55:52 GMT

     [ https://issues.apache.org/jira/browse/HBASE-2142?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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}

> While commenting on HBASE-2117 I noticed that Hadoop's NameNode has that and it makes
sense to expose it too in HBase's HMaster metrics.
