> 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.
