--------------------------------------

Yes. I agree to [~pbacsko]

Pls help to add a test case here. Other than that, approach seems fine.

> If GPU plugin is enabled for the NodeManager, it is possible to run jobs with GPU.
> However, if LinuxContainerExecutor is not configured, an NPE is thrown when calling 
> {code:java}
> GpuResourcePlugin.getNMResourceInfo{code}
> Also, there are no warns in the log if GPU is misconfigured like this.
