> yarn.nodemanager.container-monitor.procfs-tree.smaps-based-rss.enabled is not 
> taken in account by ProcfsBasedProcessTree if 
> yarn.nodemanager.container-monitor.process-tree.class is not set in the 
> configuration.
> The parameter is well taken in account if we set 
> yarn.nodemanager.container-monitor.process-tree.class to 
> org.apache.hadoop.yarn.util.ProcfsBasedProcessTree.
> This is due to the getResourceCalculatorProcessTree which fallback to os 
> specific class if no ResourceCalculatorProcessTree class is provided and in 
> the fallback we never call setConf for ProcfsBasedProcessTree
