I am interested in monitoring in a YARN application in real time via JMX. RM and NM API do provide some container level stats - state, starting time, elapsed time, etc.
How can I get more information on the containers? Turning JMX on each container will definitely help.However, the containers come and go, we might not have enough time to capture JMX. For long-running containers, JMX might be useful.
