Hadoop version: hadoop-0.20.205.0 My NN machine has 2 IP addresses and 2 hostnames assigned to them respectively. I have configured "fs.default.name" using one of the hostnames and used the cluster for a while.
Now, I may have to move the "fs.default.name" to the other IP/hostname of the same machine. If no other configurations change (such as the directories), can I simply change "fs.default.name" to the new hostname and restart NN? Thanks, James
