      New JMX Bean in ResourceManager to provide list of live node managers:

      Hadoop:service=ResourceManager,name=RMNMInfo LiveNodeManagers
      Show
      New JMX Bean in ResourceManager to provide list of live node managers: Hadoop:service=ResourceManager,name=RMNMInfo LiveNodeManagers

      Description

      In 0.20.*, the JMX UI for the JobTracker (http://<JobTrackerHost>:50030/jmx) showed lists of Live and BlackListed Nodes under the JobTrackerInfo section.

      In 0.23, the ResourceManager JMX UI shows the number of active, decommissioned, lost, unhealthy, and rebooted nodes under the ClusterMetrics section, but does not give the list of nodes.

      At least the list of active nodes is needed in JSON format.
