Trouble copying local file to hdfs
I have set-up Hadoop on OpenSuse 11.2 VM using Virtualbox. I ran Hadoop examples in the standalone mode successfully.
Now, I want to run in distributed mode using 2 nodes.
Hadoop starts fine and jps lists all the nodes. But when i try to put any file or run any example, I get error. For e.g. :
hadoop@master:~/hadoop> ./bin/hadoop dfs -copyFromLocal ./input inputsample

I can see the files on HDFS through the web interface but they are empty.
Any suggestion on how can I get over this ?
