> When NM restart, containers will be recovered. However, only memory and vcores in capability have been recovered. All resources need to be recovered.
> {code:title=ContainerImpl.java}
>       // resource capability had been updated before NM was down
>       this.resource = Resource.newInstance(recoveredCapability.getMemorySize(),
>           recoveredCapability.getVirtualCores());
> {code}
> It should be like this.
> {code:title=ContainerImpl.java}
>       // resource capability had been updated before NM was down
>       // need to recover all resources, not only <mem, vcores>
>       this.resource = Resources.clone(recoveredCapability);
> {code}
