Thanks for the response.
I have already tried moving JobTracker to several different ports always
with the same result.

You can try running JobTracker on some other port. This port might me in

All,
I'm setting up my first hadoop full cluster. I did the cygwin thing and
everything works. I'm having problems with the cluster.
The cluster is five nodes of matched hardware running Ubuntu 8.04. I
believe I have ssh working properly. The master node is named hbase1, but
I'm not doing anything with hbase.
I run start-dfs.sh, Jps shows NameNode running, and the logs are free of
error. The data nodes, however, appear to be complaining. "Retrying
connect to server: hbase1"
I run start-mapred.sh, Jps shows NameNode and JobTracker running.
The namenode log says, "jobtracker.info could only be replicated to 0
nodes,
instead of 1".
The jobtracker log says two things of significance:
1. "It might be because the JobTracker failed to read/write system files
(hdfs://hbase1:30000/hdfs/mapred/system/jobtracker.info /
hdfs://hbase1:30000/hdfs/mapred/system/jobtracker.info.recover) or the
system file hdfs://hbase1:30000/hdfs/mapred/system/jobtracker.info is
missing!"
don't worry about the job tracker until you have HDFS -that is namenodes
and datanodes, up and running. Do you have any datanodes up? Because
complaints about not enough replication and missing files mean the
filesystem isn't live yet
