I am trying to run Hadoop on a cluster of 3 nodes. The namenode and the jobtracker web UI work. I have the namenode running on node A and job tracker running on node B. Is it true that namenode and jobtracker cannot run on the same box ? Also if I want to run the examples on the cluster is there anything special that needs to be done. When I run the example WordCount on a machine C (which is a task tracker and not a job tracker) the LocalJobRunner is invoked all the time. I am guessing this means that the map tasks are running locally. How can I distribute this on the cluster ? Please advice.
Thanks Avinash
