Hi! Due to network reconfigurations, I need to change the hostnames of some of my worker nodes, i.e. the nodes running tasktracker and datanode. I need to do this to make my hostname naming schema actually concur with the network setup.
Are there any problems doing this? It seems HDFS identifies things using some kind of hostname-independent UID, so I guess it should recover from one machine going down and then appear again under another hostname?
