> {code:title=NodeManagerMetrics.java}
>   public void addResource(Resource res) {
>     availableMB = availableMB + res.getMemorySize();
>     availableGB.incr((int)Math.floor(availableMB/1024d));
>     availableVCores.incr(res.getVirtualCores());
>   }
> {code}
> When the node resource was updated through RM-NM heartbeat, the NM metric will get wrong value. 
> The root cause of this issue is that new resource has been added to availableMB, so not needed to increase for availableGB again.
