Psuedo-Distributed Mode installation failure: Need help

Hey All,

I am trying to install hadoop 0.20.2 and proceeded till daemon-start-up
bin/start-all.sh.
But I see no datanode created.

jps output:
43323 JobTracker
43281 SecondaryNameNode
43162 NameNode
43403 Jps
43381 TaskTracker
19747

Named node log:
2011-01-31 15:08:47,343 INFO org.apache.hadoop.ipc.Server: IPC Server
handler 6 on 9000, call addBlock(/tmp/hadoop-sjagannath/mapred/system/
jobtracker.info, DFSClient_-462680310) from 127.0.0.1:61167: error:

I am sure, I am doing what ever the quickstarts asks me to do.
I am following:
a.
http://hadoop-tutorial.blogspot.com/2010/11/running-hadoop-in-pseudo-distributed.html
b. http://hadoop.apache.org/common/docs/current/single_node_setup.html

I am no sure what is going on.
I would love to clear this hurdle and get my hand dirty with the actual
work.
Please let me know what is happening.


Thanks,
Sharath

Check your DataNode logs under $HADOOP_HOME/logs/. It would have the
reason why it did not start.

You can also issue `hadoop datanode` and watch the exceptional movie play.
