> With FLINK-14106, memory of a TaskExecutor is decided in two steps on active resource managers.
> - {{SlotManager}} decides {{WorkerResourceSpec}}, including memory used by Flink tasks: task heap, task off-heap, network and managed memory.
> - {{ResourceManager}} derives {{TaskExecutorProcessSpec}} from {{WorkerResourceSpec}} and the configuration, deciding sizes of memory used by Flink framework and JVM: framework heap, framework off-heap, jvm metaspace and jvm overhead.
> This works fine for now, because both {{WorkerResourceSpec}} and {{TaskExecutorProcessSpec}} are derived from the same configurations. However, it might cause problem if later we have new {{SlotManager}} implementations that decides {{WorkerResourceSpec}} dynamically. In such cases, the process/flink sizes in configuration should be ignored, or it may easily lead to configuration conflicts.
