Description

An error occurred when using a port range for the taskmanager.data.bind-port configuration item.

 

Environment Information:

• Flink version: 1.20.0
• Java: 1.8

Configuration Information:

• taskmanager.data.bind-port: 12001-13000

When starting the Flink job, an exception occurs. Please see the attached file for the exception message: exception.png

The error received is a NativeIoException. However, the source code is set up to catch a BindException. (Refer to the attached file: source_code.png) The two do not match.
