> ResourceProfile records all the resource requirements for a slot。It is generated by JobMaster and then passed to ResourceManager with the slot request.
> A task in the slot needs three parts of resource:
> 1. The resource for the operators, this is specified by the ResourceSpec user defined
> 2. The resource for the operators to communicating with their upstreams. For example, the resource for buffer pools and so on.
> 3. The resource for the operators to communicating with their downstreams. Same as above.
> So ResourceProfile should contain three parts of resource, the first part from ResouceSpec, and the other two part be generated by Job Master.
