> 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.
