zhihai xu updated YARN-2756:

Description: use static variable (Resources.none()) for not-running 
Node.resource in CommonNodeLabelsManager to save memory. When a Node is not 
activated, the resource is never used, When a Node is activated, a new resource 
will be assigned to it in RMNodeLabelsManager#activateNode (nm.resource = 
resource) So it would be better to use static variable Resources.none() instead 
of allocating a new variable(Resource.newInstance(0, 0)) for each node 
deactivation.  (was: use static variable (Resources.none()) for not-running 
Node.resource in CommonNodeLabelsManager to save memory. When a Node is not 
activated, the resource is never used, When a Node is activated, a new resource 
will be assigned to it in RMNodeLabelsManager#activateNode (nm.resource = 
resource;) So it would be better to use static variable Resources.none() 
instead of allocating a new variable(Resource.newInstance(0, 0)) for each node 
deactivation.)
