NM node updates are sent to ApplicationMaster only when NodeManager is added/removed/'change in NM state i.e Usable/Unusable'. Otherwise no updates are sent to AM even at least one time in application life time!!
I believe it is implemented purposefully to intimate AM about only unusable nodes.

I've been modifying the slider AM to wait for NM updates of node maps -but I'm not seeing any onNodesUpdated() callbacks, at least for an AM which doesn't instantiate any containers. When/how do those updates come?
