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.
