> The current Hadoop YARN resource management logic assumes per node resource
> is static during the lifetime of the NM process. Allowing run-time
> configuration on per node resource will give us finer granularity of resource
> elasticity. This allows Hadoop workloads to coexist with other workloads on
> the same hardware efficiently, whether or not the environment is virtualized.
