> Ambari's Stack Advisor has a static method to compute OS/component overheads
> when computing the YARN config 'yarn.nodemanager.resource.memory-mb' for NM
> We should add validation to check if there are any NodeManagers that would
> have high memory usage based on co-located service components and report a
> warning.
