chenyuzhi updated FLINK-32669:
------------------------------
Description:
We can setup range-port for taskmanager rpc port to avoid occupying an
unexpected port(such as the port of datanode service).
However, we can't setup range-port for taskmanager data port(config-key:
taskmanager.data.port). In production env, it's unreasonable to setup a specify
port, thus we usually not setup this configuration key.
The problem is without setup taskmanager data port, it's possible to conflict
with port of other services. Thus is it

It means still can be port conflict
