--------------------------------

             Summary: The description of taskmanager.memory.task.heap.size in the official document is incorrect
                 Key: FLINK-22963
                 URL: https://issues.apache.org/jira/browse/FLINK-22963
             Project: Flink
          Issue Type: Improvement
          Components: Documentation
    Affects Versions: 1.13.0, 1.12.0, 1.10.0
            Reporter: JasonLee


When I studied the memory model of TaskManager, I found that there is a problem in the official document, which is the description of taskmanager.memory.task.heap.size is incorrect.

According to the official memory model, I think the correct description should be that task Heap Memory size for TaskExecutors. This is the size of JVM heap memory reserved for tasks. If not specified, it will be derived as Total Flink Memory minus Framework Heap Memory, Framework Off-Heap Heap Memory, Task Off-Heap Memory, Managed Memory and Network Memory.

However, in the official document, the Framework Off-Heap Heap Memory should be subtracted.
