What type of enhancement is this?

Configuration

What does the enhancement do?

Standardize the option names across Datanode, Frontend, and Metasrv. Currently, some options have the same meaning but different names.
For example:

• Datanode has rpc_hostname, but in Metasrv it is called server_addr.
• Frontend and Datanode use rpc_addr, but in Metasrv, it's called bind_addr.

Apart from the startup command options, there are similar issues with the parameters in the configuration file.

Implementation challenges

It is a breaking change
