I have a 18 node cluster that ha= d to be physically moved.

Unfortunately all the ip addresses were lost = (recreated).

This must have happened to someone be= fore.

Nothing else on the machines has been changed. Most importa= ntly the data in HDFS is still sitting there.

Is t= here a way to recover this cluster to a useable state?

thanks

John
