----------------------------------------------------------------
Thanks [~gandras] for the patch.
1. Why we need a separate StateDump if most of the metrics are already exposed
via RMWebService /ws/v1/cluster/scheduler. Sorry, did not think about this when
raising the Jira. It is unnecessary effort to get and display metrics at both
the places.
Most of the useful metrics are already captured in scheduler response, it is
better to add missing ones into the same instead of rewriting a new one. Thanks.

> CapacityScheduler dump with Scheduler, FiCaSchedulerNode, FiCaSchedulerApp,
> ParentQueue, LeafQueue, app and queue level ordering, multi node lookup
> ordering details will make it ease to debug scheduler related issues instead
> of correlating Debug Logs with CapacityScheduler code to get values for the
> above.
> This is similar to FairScheduler statedump YARN-6042.
