Thanks guys, everything appeared to go smoothly, but i'm getting stuck on Protocol org.apache.hadoop.hdfs.protocol.ClientProtocol version mismatch. (client = 42, server = 41)
And thus the master won't start up. I upgraded Hadoop to 0.20.2. Anything to try aside from that? I googled around and only saw this error come up in the context of 0.90.0 rc2.
