Github user shuai-xu commented on the issue: https://github.com/apache/flink/pull/4911 @tillrohrmann, Yes, the Resource is a little too generic and prone to typos. However, the resource are various and closely related to the platform(YARN/MESOS), only a GPUResource and FPGAResource may not satisfy user's need. For example, we have at lease two types of FPGA resources in our cluster. And it could consider the users who need to specify extended resources as advanced users. General users only need to know vcore and memory, which are already defined in ResurceSpec. Advanced users should be familiar with not only flink but also the resource platform. They should know the resources types YARN/MESOS supports. And, If flink resource manager passes all the extended resource to YARN/MESOS when starting a container, it need not change when adding a new resource type only if YARN/MESOS can recognize it from extended resources. There has to be a compromise between extendibility and ease of use. I suggest we can add a general GPUResource and FPGAResource for general use while st ill keeping the Resource for extension. Does this make sense?
