Jianbin Chen commented on KAFKA-17068:
--------------------------------------
I found the reason. It's because I forgot to stop the node at 192.168.1.123,
while I had already changed the other two brokers to 192.168.1.126. Starting
192.168.1.126 resulted in failure. Is there any way to optimize this situation?
Otherwise, it's a bit misleading and could lead to confusion during
troubleshooting
