Peter Bacsko commented on YARN-9677:
------------------------------------

Thanks for the patch [~pingsutw]. Looks like a straightforward refactor. 
+1 (non-binding) 

> Make FpgaDevice and GpuDevice classes more similar to each other

> org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.resources.fpga.FpgaResourceAllocator.FpgaDevice
>  is an inner class of FpgaResourceAllocator.
> It is not only being used from its parent class but from other classes as 
> well so we are losing the purpose of the inner class, it does not really make 
> sense.
> We also have 
> org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin.gpu.GpuDevice
>  which is a similar class, but for GPU devices.
> What we could do here is to make FpgaDevice a single class and harmonize the 
> packages of these 2 classes, meaning they should be "closer" to each other in 
> terms of packaging.
