But we're use DHCP network, and the ip address might be changed after the cluster is created. Either while the node is restarted, or the IP address of one node might be changed directly by DHCP server. So I want to know if there is easy solution from Ambari to handle such issue. The ip change might happen for all of nodes, including name node, jobtracker/resource manager, etc. I didn't get any information for this topic from the Ambari document. Your any comment is appreciated. thanks, Emma
