> 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)
