> now only total reserved memory/Vcores are exposed at RM webUI, reserved 
> memory/Vcores of a single nodemanager is hard to find out. it confuses users 
> that they obeserve that there are available memory/Vcores at nodes page, but 
> their jobs are stuck and waiting for resouce to be allocated. It is helpful 
> for bedug to expose reserved memory/Vcores of every single nodemanager, and 
> memory/Vcores that can be allocated( unallocated minus reserved)
