Luke Lu commented on MAPREDUCE-4944:
------------------------------------
We don't need to use JMX-RMI directly, rather a JMX REST API. Either /jmx or
/jolokia (after HADOOP-9160) would work with regular http port from the
configs. The legacy /jmx already have these information.
> Backport YARN-40 to support listClusterNodes and printNodeStatus in command
