> At present, we support GPU/FPGA device in YARN through a native, coupling way. But it's difficult for a vendor to implement such a device plugin because the developer needs much knowledge of YARN internals. And this brings burden to the community to maintain both YARN core and vendor-specific code.
> Here we propose a new device plugin framework to ease vendor device plugin development and provide a more flexible way to integrate with YARN NM.
