Cluster lost IP addresses
I have a 18 node cluster that had to be physically moved.Unfortunately all the ip addresses were lost (recreated).
This must have happened to someone before.Nothing else on the machines has been changed. Most importantly the data in HDFS is still sitting there.
Is there a way to recover this cluster to a useable state?thanksJohn
