----------------------------------
[~tangzhankun],
I'm not quite sure about what does the first-class citizen means? In my mind
all supported resource types committed to YARN are first-class citizen.
For every new added resource types which need to be isolated/enforced in NM
side, it will be unavoidably to change at least ResourceHandler (so only add
.so is not enough), and for resource type needs additional permissions, c-e
changes are required. This is because model of different resource types are
quite different, for example, GPU supports need to use binaries like nvidia-smi
to detect host OS's GPU information, but FPGA may not need. And IIUC, NUMA
support only needs ResourceHandler changes but don't need changes to c-e.
