     ### TaskManager
     
    -The following parameters configure Flink's TaskManagers.
    -
    -
    -- `taskmanager.hostname`: The hostname of the network interface that the 
TaskManager binds to. By default, the TaskManager searches for network 
interfaces that can connect to the JobManager and other TaskManagers. This 
option can be used to define a hostname if that strategy fails for some reason. 
Because different TaskManagers need different values for this option, it 
usually is specified in an additional non-shared TaskManager-specific config 
file.
    -
    -- `taskmanager.rpc.port`: The task manager's IPC port (DEFAULT: **0**, 
which lets the OS choose a free port). Flink also accepts a list of ports 
("50100,50101"), ranges ("50100-50200") or a combination of both. It is 
recommended to set a range of ports to avoid collisions when multiple 
TaskManagers are running on the same machine.
    -
    -- `taskmanager.data.port`: The task manager's port used for data exchange 
operations (DEFAULT: **0**, which lets the OS choose a free port).
    -
    -- `taskmanager.data.ssl.enabled`: Enable SSL support for the taskmanager 
data transport. This is applicable only when the global ssl flag 
security.ssl.enabled is set to true (DEFAULT: **true**)

    Why don't we keep `This is applicable only when the global ssl flag 
security.ssl.enabled is set to true`?
