Description

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.
