---------------------------------
Summary: Support port-range for taskmanager data port
Key: FLINK-32669
URL: https://issues.apache.org/jira/browse/FLINK-32669
Project: Flink
Issue Type: Improvement
Components: Runtime / Network
Reporter: chenyuzhi
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 can conflict with port
of other services .
It means still can be port conflict
不合理
