--------------------------------------------------------------
[~wangda], Thanks for the great effort. I'll implement the FPGA resource
plugin(only supports OpenCL FPGA application for now) based on that.
One question is that in above discussions you mentioned the GPU is a mandatory
resource like cpu and memory, but what's the difference between mandatory and
first-class resource? And a list of first-class resource? Currently, If I
understand correctly,
1. First-class resource should be parsed from resource-types.xml and
node-resources.xml(or auto discover) instead of yarn-site.xml?
2. First-calss resource handler should register itself with the same resource
name defined in xml files?
3. First-class resource should be shown in a separate user-defined column in
web pages?
