Resending...I think my message got bounced earlier:

Thanks Philippe.
Yeah, sorry, I should I have mentioned that I tried using the hostname
of my machine first, so I had the following hadoop-site.xml settings.
<property>
<name>fs.default.name</name>
<value>tiger.stanford.edu:9000</value>
</property>
<!-- map/reduce properties -->
<property>
<name>mapred.job.tracker</name>
<value>tiger.stanford.edu:9001</value>
</property>
But that still didn't work:
tiger$ bin/hadoop jar hadoop-0.12.2-examples.jar wordcount input_dir output_dir
07/03/26 01:57:25 INFO ipc.Client: Retrying connect to server:

xx.yy.zz.aa:9000. Already tried 10 time(s).
java.lang.RuntimeException: java.net.ConnectException: Connection refused
Separately Arun - I did have passphrase-less ssh enabled on this machine.
i.e., I executed:
ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
