lining commented on FLINK-14435:
--------------------------------
The previous configuration doesn't fully reflect the memory model of the task
manager. If the user chooses to configure the task manager's total memory, he
doesn't know how Flink allocates memory to heap/native/direct memory
internally. But if the user chooses to specify each part and the total
explicitly, then there's a possibility that the sum up of the part doesn't
match to the whole, then the job won't be started normally.
> Add TaskManageResourceInfo which match the memory compositions of taskmanager
