How to run Word Count example on Hadoop MapReduce (WordCount Tutorial)

You can download the code I used in the tutorial from here:

Thank you for this tutorial.. But the command "hadoop dfs -cat /HDFS OUTPUT DIRECTORY/* doesn't work in my VM.. I have a warning message of deprecated and attempting to execute replacement "hdfs dfs" instead. Can you give me the alternative command please?

Is this MapReduce created on multinode cluster ?

[sudeshnareddy]

Do we have to run all these commands on the user in which we have installed hadoop or the root user is fine?
