Hadoop pseudo-distributed mode error - hadoop

Question

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

Answer 1

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 .

Answer 2

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?

Answer 3

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.
