Arun Suresh commented on YARN-7953:
-----------------------------------
[~curino], Thanks for working on this.
I am thinking though, there might be a far easier way to encapsulate send
Scheduler State.
* A Scheduler maintains QueueMetrics, which itself is hierarchical.
* The queuemetrics for all queues are query-able via the JMX console as simple
KV pairs.
* The GPG just needs to periodically pull the queue-metrics of each
participation RM in the federation and for each key, diff with the previous
value it received - which will result in the delta - which is what we are
interested in I believe.
