             Summary: The description of taskmanager.memory.task.heap.size in 
the official document is incorrect
                 Key: FLINK-25599
                 URL: https://issues.apache.org/jira/browse/FLINK-25599
             Project: Flink
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.11.6, 1.10.3
            Reporter: Zhuang Liu 


When I read 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.

 If not specified, it will be derived as Total Flink Memory minus Framework 
Heap Memory, Framework Off-Heap Memory, Task Off-Heap Memory, Managed Memory 
and Network Memory.

However, in the official document, derived as Total Flink Memory minus 
Framework Heap Memory, Task Off-Heap Memory, Managed Memory and Network 
Memory.Hence, Framework Off-Heap Memory is missing.
