I think we should make sure that Flink still works also if you don't have a
resource profile specified. Maybe introducing a resource profile which matches
all other resource profiles or by trying to derive it somehow.
> Resource should be strictly matched when allocating for yarn

> In flip6, for yarn mode, resource should be assigned as requested to avoid
> resource wasting and OOM.
> 1. YarnResourceManager will request container according to ResourceProfile
> in slot request form JM.
> 2. RM will pass the ResourceProfile to TM for initializing its slots.
> 3. RM should match the slots offered by TM with SlotRequest from JM strictly.
