Hadoop pseudo-distributed mode error

I have set-up Hadoop on a OpenSuse 11.2 VM using Virtualbox.I have made the prerequisite configs. I ran this example in the Standalone mode successfully. But in psuedo-distributed mode I get the following error:

$./bin/hadoop fs -put conf input

It seems like there are no live data nodes in the cluster. Did you check whether status page shows live nodes? http://localhost:50070/

Start all Hadoop daemons using command $ bin/start-all.sh .

Did you start the Hadoop demons. This needs to be done in psuedo-dist mode unlike the standalone mode. You start them using something like:

$bin\start-all.sh

Documentation for the steps required can be found here.

Did you follow all these steps? Can you browse the NameNode and JobTracker web interfaces?

Maybe try using preconfigured virtual machine? http://www.cloudera.com/developers/downloads/virtual-machine/ I think this is probably the best way to start learning hadoop, and those problems should not happened there.
