Hi, Today Julian and I discussed some logic of the cluster module. Both of us feel it strange that we replace the hostname to IP before a cluster node starts up. I think it is not a very common way.
hostname sometimes is very very helpful. For example, in K8S environment, a node's hostname never changes, but its IP may change. Best, ----------------------------------- Xiangdong Huang School of Software, Tsinghua University 黄向东 清华大学 软件学院
