Subject Re: I can run hadoop,
Date Mon, 05 Jan 2009 04:16:15 GMT
org.apache.hadoop.hdfs.server.datanode.DataNode: java.io.IOException: Call
to /192.168.1.55:9000 failed on local exception: No route to host

It sounds like 192.168.1.102 cannot see the master at 192.168.1.55. Can you
ping or ssh from .102 to .55?
