研究方向

First, locate the yb admin source code in the repository (likely in the `bin/yb admin` or similar directory). Investigate how master addresses are currently being passed to yb admin (e.g., via command line arguments). Then, find examples of config file parsing in the codebase to mimic the pattern (e.g., using a library like boost::property tree for INI/JSON parsing). The server.conf file format needs to be inferred from existing documentation or sample config files. Implement a fallback mechanism that reads the master addresses from a server.conf file if no command line flags are provided.
