------------------------------------------------------------
[~jianghuazhu], thanks for your help on debugging!
bq. 1. ... After starting s3 and s4 subsequently, ...
This is a bug in the test. It starts with 1 server s0 and then adds two new
servers s3 and s4. The change is a majority-add which should be disallowed;
see RATIS-1930. We could simply start with 3 servers in the beginning. Then
adding 2 new servers is fine.
bq. 2. When the client sends the setConfiguration() command, it cannot
establish a connection with s3 or s4. ...
It seems that the servers were starting and RPC ports were not yet ready. The
client would retry so it should not be a problem.
