-Re: Two Datanodes - Incompatible Cluster IDs

If you just blow away the contents of the dfs.data.dir directories then start the DataNode daemon again you should be fine. (That's where the ClusterID is stored. When they next connect to the NameNode, because they don't have one now that you've deleted it, they'll be given the one from the NameNode.)
